Abstract: Abstract Background Some chromatinopathies may present with common clinical findings (intellectual disability, brain and limb malformation, facial dysmorphism). Furthermore, one of their cardinal shared features is growth dysregulation.We aimed to assess and deepen this resemblance in three specific conditions, namely Wiedemann-Steiner (WDSTS), Kleefstra (KLEFS1) and Coffin-Siris syndrome (CSS1), with a particular focus on possible metabolic roots. Methods Eleven patients were enrolled, three with WDSTS, five with KLEFS1 and three with CSS1, referring to Fondazione IRCCS Ca’ Granda Ospedale Maggiore, Milan, Italy. We performed both a physical examination with detailed anthropometric measurements and an evaluation of the patients’ REE (rest energy expenditure) by indirect calorimetry, comparing the results with age- and sex-matched healthy controls. Results We observed new clinical features and overlap between these conditions suggesting that different disturbances of epigenetic machinery genes can converge on a common effect, leading to overlapping clinical phenotypes. The REE was not distinguishable between the three conditions and healthy controls. Conclusions Epigenetic machinery plays an essential role both in growth regulation and in neurodevelopment; we recommend evaluating skeletal [craniovertebral junction abnormalities (CVJ) polydactyly], otolaryngological [obstructive sleep apnea syndrome (OSAs), recurrent otitis media], dental [tooth agenesis, talon cusps], and central nervous system (CNS) [olfactory bulbs and cerebellum anomalies] features. These features could be included in monitoring guidelines. Further studies are needed to deepen the knowledge about energy metabolism.

2. From clinical to molecular diagnosis: relevance of diagnostic strategy in two cases of branchio-oto-renal syndrome – case report

Author: Elena Cacciatori, Sebastiano Aleo, Giulietta Scuvera, Chiara Rigon, Paola Giovanna Marchisio, Matteo Cassina, and Donatella Milani
Subjects: Branchio-oto-renal syndrome, Deafness, EYA1, Copy number variation – case report, Pediatrics, RJ1-570
Abstract: Abstract Background Branchio-oto-renal syndrome (BOR) is an autosomal dominant disorder characterized by deafness, branchiogenic malformations and renal abnormalities. Pathogenic variants in EYA1, SIX1 and SIX5 genes cause almost half of cases; copy number variants (CNV) and complex genomic rearrangements have been revealed in about 20% of patients, but they are not routinely and commonly included in the diagnostic work-up. Case presentation We report two unrelated patients with BOR syndrome clinical features, negative sequencing for BOR genes and the identification of a 2.65 Mb 8q13.2–13.3 microdeletion. Conclusions We highlight the value of CNV analyses in high level of suspicion for BOR syndrome but negative sequencing for BOR genes and we propose an innovative diagnostic flow-chart to increase current detection rate. Our report confirms a mechanism of non-allelic homologous recombination as causing this recurrent 8q13.2–13.3 microdeletion. Moreover, considering the role of PRDM14 and NCOA2 genes, both involved in regulation of fertility and deleted in our patients, we suggest the necessity of a longer follow-up to monitor fertility issues or additional clinical findings.

Abstract: Abstract Background Choline kinase beta (CHKB) catalyzes the first step in the de novo biosynthesis of phosphatidyl choline and phosphatidylethanolamine via the Kennedy pathway. Derangement of this pathway might also influence the homeostasis of mitochondrial membranes. Autosomal recessive CHKB mutations cause a rare form of congenital muscular dystrophy known as megaconial congenital muscular dystrophy (MCMD). Case presentation We describe a novel proband presenting MCMD due to unpublished CHKB mutations. The patient is a 6-year-old boy who came to our attention for cognitive impairment and slowly progressive muscular weakness. He was the first son of non-consanguineous healthy parents from Sri Lanka. Neurological examination showed proximal weakness at four limbs, weak osteotendinous reflexes, Gowers’ maneuver, and waddling gate. Creatine kinase levels were mildly increased. EMG and brain MRI were normal. Left quadriceps skeletal muscle biopsy showed a myopathic pattern with nuclear centralizations and connective tissue increase. Histological and histochemical staining suggested subsarcolemmal localization and dimensional increase of mitochondria. Ultrastructural analysis confirmed the presence of enlarged (“megaconial”) mitochondria. Direct sequencing of CHKB identified two novel defects: the c.1060G > C (p.Gly354Arg) substitution and the c.448-56_29del intronic deletion, segregating from father and mother, respectively. Subcloning of RT-PCR amplicons from patient’s muscle RNA showed that c.448-56_29del results in the partial retention (14 nucleotides) of intron 3, altering physiological splicing and transcript stability. Biochemical studies showed reduced levels of the mitochondrial fission factor DRP1 and the severe impairment of mitochondrial respiratory chain activity in patient’s muscle compared to controls. Conclusions This report expands the molecular findings associated with MCMD and confirms the importance of considering CHKB variants in the differential diagnosis of patients presenting with muscular dystrophy and mental retardation. The clinical outcome of MCMD patients seems to be influenced by CHKB molecular defects. Histological and ultrastructural examination of muscle biopsy directed molecular studies and allowed the identification and characterization of an intronic mutation, usually escaping standard molecular testing.

Abstract: Usually overlooked by physicians, olfactory abnormalities are not uncommon. Olfactory malformations have recently been reported in an emerging group of genetic disorders called Mendelian Disorders of the Epigenetic Machinery (MDEM). This study aims to determine the prevalence of olfactory malformations in a heterogeneous group of subjects with MDEM. We reviewed the clinical data of 35 patients, 20 females and 15 males, with a mean age of 9.52 years (SD 4.99). All patients had a MDEM and an already available high-resolution brain MRI scan. Two experienced neuroradiologists reviewed the MR images, noting abnormalities and classifying olfactory malformations. Main findings included Corpus Callosum, Cerebellar vermis, and olfactory defects. The latter were found in 11/35 cases (31.4%), of which 7/11 had Rubinstein-Taybi syndrome (RSTS), 2/11 had CHARGE syndrome, 1/11 had Kleefstra syndrome (KLFS), and 1/11 had Weaver syndrome (WVS). The irregularities mainly concerned the olfactory bulbs and were bilateral in 9/11 patients. With over 30% of our sample having an olfactory malformation, this study reveals a possible new diagnostic marker for MDEM and links the epigenetic machinery to the development of the olfactory bulbs.

Subjects: 9q22.3 microdeletion syndrome, craniosynostosis, Gorlin syndrome, PTCH1, Genetics, QH426-470
Abstract: Abstract Background Gorlin syndrome, also known as basal cell nevus syndrome (BCNS), is a rare autosomal dominant genetic condition, characterized by the presence of multiple basal cell carcinomas at a young age, odontogenic keratocysts, skeletal anomalies, macrocephaly, and dysmorphisms. BCNS is mainly caused by mutations in PTCH1, an onco‐suppressor gene that maps at 9q22.3 region. A disease related to BCNS is the 9q22.3 microdeletion syndrome. This condition has an overlapping clinical phenotype with the BCNS, but it can present in addition: metopic craniosynostosis, overgrowth, obstructive hydrocephalus, developmental delay, intellectual disability, and seizures. This syndrome is caused by the deletion of a genomic region containing the PTCH1 and the FANCC. Methods and Results We report the case of an 11‐year‐old girl that came to our attention for overgrowth, dysmorphic features of the face, and craniosynostosis, but with a normal intellectual and motor development. At first we performed an array‐comparative genomic hybridization (aCGH) analysis. The analysis showed no copy number changes. Then, we performed the analysis of the PTCH1 by next‐generation sequencing. This analysis showed a heterozygous frameshift mutation. Conclusion This is the first case with a PTCH1 point mutation with a 9q22.3 microdeletion syndrome phenotype. This finding may strengthen the importance of the role of the PTCH1, especially regarding the metopic craniosynostosis.

Abstract: While interplay between BRCA1 and AURKA-RHAMM-TPX2-TUBG1 regulates mammary epithelial polarization, common genetic variation in HMMR (gene product RHAMM) may be associated with risk of breast cancer in BRCA1 mutation carriers. Following on these observations, we further assessed the link between the AURKA-HMMR-TPX2-TUBG1 functional module and risk of breast cancer in BRCA1 or BRCA2 mutation carriers. Forty-one single nucleotide polymorphisms (SNPs) were genotyped in 15,252 BRCA1 and 8,211 BRCA2 mutation carriers and subsequently analyzed using a retrospective likelihood approach. The association of HMMR rs299290 with breast cancer risk in BRCA1 mutation carriers was confirmed: per-allele hazard ratio (HR) = 1.10, 95% confidence interval (CI) 1.04-1.15, p = 1.9 x 10(-4) (false discovery rate (FDR)-adjusted p = 0.043). Variation in CSTF1, located next to AURKA, was also found to be associated with breast cancer risk in BRCA2 mutation carriers: rs2426618 per-allele HR = 1.10, 95% CI 1.03-1.16, p = 0.005 (FDR-adjusted p = 0.045). Assessment of pairwise interactions provided suggestions (FDR-adjusted pinteraction values > 0.05) for deviations from the multiplicative model for rs299290 and CSTF1 rs6064391, and rs299290 and TUBG1 rs11649877 in both BRCA1 and BRCA2 mutation carriers. Following these suggestions, the expression of HMMR and AURKA or TUBG1 in sporadic breast tumors was found to potentially interact, influencing patients' survival. Together, the results of this study support the hypothesis of a causative link between altered function of AURKA-HMMR-TPX2-TUBG1 and breast carcinogenesis in BRCA1/2 mutation carriers.

Abstract: Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of synthetic lethality that exists between one of the components of the BER pathway, PARP1 (poly ADP ribose polymerase), and both BRCA1 and BRCA2. In the present study, we have performed a comprehensive analysis of 18 genes involved in BER using a tagging SNP approach in a large series of BRCA1 and BRCA2 mutation carriers. 144 SNPs were analyzed in a two stage study involving 23,463 carriers from the CIMBA consortium (the Consortium of Investigators of Modifiers of BRCA1 and BRCA2). Eleven SNPs showed evidence of association with breast and/or ovarian cancer at p

Abstract: Whole-Exome Sequencing (WES) is a valuable tool for the molecular diagnosis of patients with a suspected genetic condition. In complex and heterogeneous diseases, the interpretation of WES variants is more challenging given the absence of diagnostic handles and other reported cases with overlapping clinical presentations.To describe candidate variants emerging from trio-WES and possibly associated with the clinical phenotype in clinically heterogeneous conditions.We performed WES in ten patients from eight families, selected because of the lack of a clear clinical diagnosis or suspicion, the presence of multiple clinical signs, and the negative results of traditional genetic tests.Although we identified ten candidate variants, reaching the diagnosis of these cases is challenging, given the complexity and the rarity of these syndromes and because affected genes are already associated with known genetic diseases only partially recapitulating patients' phenotypes. However, the identification of these variants could shed light into the definition of new genotype-phenotype correlations. Here, we describe the clinical and molecular data of these cases with the aim of favoring the match with other similar cases and, hopefully, confirm our diagnostic hypotheses.This study emphasizes the major limitations associated with WES data interpretation, but also highlights its clinical utility in unraveling novel genotype-phenotype correlations in complex and heterogeneous undefined clinical conditions with a suspected genetic etiology.

Abstract: Background:BRCA1 and BRCA2 mutation carriers are at substantially increased risk for developing breast and ovarian cancer. The incomplete penetrance coupled with the variable age at diagnosis in carriers of the same mutation suggests the existence of genetic and nongenetic modifying factors. In this study, we evaluated the putative role of variants in many candidate modifier genes.Methods: Genotyping data from 15,252 BRCA1 and 8,211 BRCA2 mutation carriers, for known variants (n = 3,248) located within or around 445 candidate genes, were available through the iCOGS custom-designed array. Breast and ovarian cancer association analysis was performed within a retrospective cohort approach.Results: The observed P values of association ranged between 0.005 and 1.000. None of the variants was significantly associated with breast or ovarian cancer risk in either BRCA1 or BRCA2 mutation carriers, after multiple testing adjustments.Conclusion: There is little evidence that any of the evaluated candidate variants act as modifiers of breast and/or ovarian cancer risk in BRCA1 or BRCA2 mutation carriers.Impact: Genome-wide association studies have been more successful at identifying genetic modifiers of BRCA1/2 penetrance than candidate gene studies.

Abstract: Silver Russell Syndrome (SRS, MIM #180860) is a rare growth retardation disorder in which clinical diagnosis is based on six features: pre- and postnatal growth failure, relative macrocephaly, prominent forehead, body asymmetry, and feeding difficulties (Netchine–Harbison clinical scoring system (NH-CSS)). The molecular mechanisms consist in (epi)genetic deregulations at multiple loci: the loss of methylation (LOM) at the paternal H19/IGF2:IG-DMR (chr11p15.5) (50%) and the maternal uniparental disomy of chromosome 7 (UPD(7)mat) (10%) are the most frequent causes. Thus far, about 40% of SRS remains undiagnosed, pointing to the need to define the rare mechanisms in such a consistent fraction of unsolved patients. Within a cohort of 176 SRS with an NH-CSS ≥ 3, a molecular diagnosis was disclosed in about 45%. Among the remaining patients, we identified in 3 probands (1.7%) with UPD(20)mat (Mulchandani–Bhoj–Conlin syndrome, OMIM #617352), a molecular mechanism deregulating the GNAS locus and described in 21 cases, characterized by severe feeding difficulties associated with failure to thrive, preterm birth, and intrauterine/postnatal growth retardation. Our patients share prominent forehead, feeding difficulties, postnatal growth delay, and advanced maternal age. Their clinical assessment and molecular diagnostic flowchart contribute to better define the characteristics of this rare imprinting disorder and to rank UPD(20)mat as the fourth most common pathogenic molecular defect causative of SRS.

Abstract: Background Living with a rare disease has profound effects on the patient's life and that of their entire family, with practical and psychosocial consequences. This is particularly true when the patient is a child. The principal aim of this study was to measure the family burden in Epidermolysis Bullosa (EB). The secondary endpoint was to evaluate the possible correlation between family burden and the severity of EB. Methods A sample of 50 families with one or two children affected by EB were recruited between January 2016 and February 2017 to answer a 20 item questionnaire - the EB Burden of Disease (EB-BoD) - developed and validated to assess the family burden of children with EB. Results The presence of a child with EB may have profound negative implications on several different areas of daily life. In particular, the results demonstrate important differences between the different subtypes of epidermolysis bullosa regarding most of the categories considered by the questionnaire. For three categories out of four (family life, child's life, economic and social impact), a higher score is observed for children with the more debilitating forms of EB: Recessive Dystrophic EB (RDEB) and Junctional EB (JEB). Conclusions Hence, it is important to work with patients and their families to identify and strengthen adaptive and coping behaviors. That is possible only through the synergistic working of a multidisciplinary team made up of experienced doctors, psychologists, and social workers while in contact with patient Associations.

Abstract: Usually overlooked by physicians, olfactory abnormalities are not uncommon. Olfactory malformations have recently been reported in an emerging group of genetic disorders called Mendelian Disorders of the Epigenetic Machinery (MDEM). This study aims to determine the prevalence of olfactory malformations in a heterogeneous group of subjects with MDEM. We reviewed the clinical data of 35 patients, 20 females and 15 males, with a mean age of 9.52 years (SD 4.99). All patients had a MDEM and an already available high-resolution brain MRI scan. Two experienced neuroradiologists reviewed the MR images, noting abnormalities and classifying olfactory malformations. Main findings included Corpus Callosum, Cerebellar vermis, and olfactory defects. The latter were found in 11/35 cases (31.4%), of which 7/11 had Rubinstein-Taybi syndrome (RSTS), 2/11 had CHARGE syndrome, 1/11 had Kleefstra syndrome (KLFS), and 1/11 had Weaver syndrome (WVS). The irregularities mainly concerned the olfactory bulbs and were bilateral in 9/11 patients. With over 30% of our sample having an olfactory malformation, this study reveals a possible new diagnostic marker for MDEM and links the epigenetic machinery to the development of the olfactory bulbs.

Abstract: Neurofibromatosis type 1 (NF1) displays overlapping phenotypes with other neurocutaneous diseases such as Legius Syndrome. Here, we present results obtained using a next generation sequencing (NGS) panel including NF1, NF2, SPRED1, SMARCB1, and LZTR1 genes on Ion Torrent. Together with NGS, the Multiplex Ligation-Dependent Probe Amplification Analysis (MLPA) method was performed to rule out large deletions/duplications in NF1 gene, we validated the MLPA/NGS approach using Sanger sequencing on DNA or RNA of both positive and negative samples. In our cohort, a pathogenic variant was found in 175 patients, the pathogenic variant was observed in NF1 gene in 168 cases. A SPRED1 pathogenic variant was also found in one child and in a one year old boy, both NF2 and LZTR1 pathogenic variants were observed, in addition, we identified five LZTR1 pathogenic variants in three children and two adults. Six NF1 pathogenic variants, that the NGS analysis failed to identify, were detected on RNA by Sanger. NGS allows the identification of novel mutations in five genes in the same sequencing run, permitting unambiguous recognition of disorders with overlapping phenotypes with NF1 and facilitating genetic counseling and a personalized follow-up.

Abstract: Kleefstra syndrome (KS) is a rare genetic condition resulting from either 9q34.3 microdeletions or mutations in the EHMT1 gene located in the same genomic region. To date, approximately 100 patients have been reported, thereby allowing the core phenotype of KS to be defined as developmental delay/intellectual disability, generalized hypotonia, neuropsychiatric anomalies, and a distinctive facial appearance. Here, to further expand the knowledge on genotype and phenotype of this condition, we report 2 novel cases: one patient carrying a 46-kb 9q34.3 deletion and showing macrocephaly never described in KS, and a second patient carrying a classic 9q34.3 deletion, presenting with a previously unreported skeletal feature (postaxial polydactyly of the right foot) and an unusual brain anomaly (olfactory bulb hypoplasia) observed via magnetic resonance imaging. Further, we provide a review of the current literature regarding KS and compare these 2 patients with those previously described, thereby confirming that the genotype-phenotype correlation in KS remains difficult to determine.

Abstract: Neurofibromatosis type I (NF1) microdeletion syndrome, which is present in 4-11% of NF1 patients, is associated with a severe phenotype as it is caused by the deletion of NF1 and other genes in the 17q11.2 region. The variable expressivity of the disease makes it challenging to establish genotype-phenotype correlations, which also affects prognosis and counselling. We here describe a 3-year-old NF1 patient with an atypical deletion and a complex phenotype. The patient showed overgrowth, café au lait spots, inguinal freckling, and neurological abnormalities. The extent of the deletion was determined by means of array comparative genomic hybridisation, and its breakpoints were isolated by means of long-range polymerase chain reaction. Sequence analysis of the deletion junction fragment revealed the occurrence of an Alu-mediated recombination that led to the generation of a chimeric gene consisting of three exons of RNF135 and eleven exons of SUZ12. Interestingly, the deletion shares a common RNF135-centred region with another deletion described in a non-NF1 patient with overgrowth. In comparison with the normal RNF135 allele, the chimeric transcript was 350-fold over-expressed in peripheral blood, and the ADAP2 gene located upstream of RNF135 was also up-regulated. In line with this, the deletion causes the loss of a chromatin TD boundary, which entails the aberrant adoption of distal cis-acting regulatory elements. These findings suggest that RNF135 haploinsufficiency is related to overgrowth in patients with NF1 microdeletion syndrome and, for the first time, strongly indicate a position effect that warrants further genotype-phenotype correlation studies to investigate the possible existence of previously unknown pathogenic mechanisms.

Abstract: The occurrence of optic pathway gliomas (OPGs) in children with neurofibromatosis type 1 (NF1) still raises many questions regarding screening and surveillance because of the lack of robust prognostic factors. Recent studies of an overall cohort of 381 patients have suggested that the genotype may be the main determinant of the development of OPG, with the risk being higher in patients harbouring NF1 mutations in the 5&rsquo, tertile and the cysteine/serine-rich domain. In an attempt to confirm this hypothesis, we used strict criteria to select a large independent cohort of 309 NF1 patients with defined constitutional NF1 mutations and appropriate brain images (255 directly enrolled and 54 as a result of a literature search). One hundred and thirty-two patients had OPG and 177 did not. The association of the position (tertiles and functional domains) and type of NF1 mutation with the development of OPG was analysed using the &chi, 2 test and Fisher&rsquo, s exact probability test, odds ratios (ORs) with 95% confidence intervals were calculated, and Bonferroni&rsquo, s correction for multiple comparisons was applied, multiple logistic regression was also used to study genotype&ndash, phenotype associations further. Our findings show no significant correlation between the site/type of NF1 mutation and the risk of OPG, and thus do not support the hypothesis that certain constitutional mutations provide prognostic information in this regard. In addition, we combined our cohort with a previously described cohort of 381 patients for a total of 690 patients and statistically re-analysed the results. The re-analysis confirmed that there were no correlations between the site (tertile and domain) and the risk of OPG, thus further strengthening our conclusions.

Abstract: Background Gorlin syndrome, also known as basal cell nevus syndrome (BCNS), is a rare autosomal dominant genetic condition, characterized by the presence of multiple basal cell carcinomas at a young age, odontogenic keratocysts, skeletal anomalies, macrocephaly, and dysmorphisms. BCNS is mainly caused by mutations in PTCH1, an onco‐suppressor gene that maps at 9q22.3 region. A disease related to BCNS is the 9q22.3 microdeletion syndrome. This condition has an overlapping clinical phenotype with the BCNS, but it can present in addition: metopic craniosynostosis, overgrowth, obstructive hydrocephalus, developmental delay, intellectual disability, and seizures. This syndrome is caused by the deletion of a genomic region containing the PTCH1 and the FANCC. Methods and Results We report the case of an 11‐year‐old girl that came to our attention for overgrowth, dysmorphic features of the face, and craniosynostosis, but with a normal intellectual and motor development. At first we performed an array‐comparative genomic hybridization (aCGH) analysis. The analysis showed no copy number changes. Then, we performed the analysis of the PTCH1 by next‐generation sequencing. This analysis showed a heterozygous frameshift mutation. Conclusion This is the first case with a PTCH1 point mutation with a 9q22.3 microdeletion syndrome phenotype. This finding may strengthen the importance of the role of the PTCH1, especially regarding the metopic craniosynostosis., We report the case of an 11‐year‐old girl that came to our attention for overgrowth, dysmorphic features of the face and craniosynostosis, but with a normal intellectual and motor development. This is the first case with a PTCH1 point mutation with a 9q22.3 microdeletion syndrome phenotype.

Abstract: Cutis Verticis Gyrata-Intellectual Disability (CVG-ID) syndrome is a rare neurocutaneous syndrome characterized by intellectual disability and scalp folds and furrows that are typically absent at birth and are first noticed after puberty. First reported in 1893, the syndrome was mainly identified in subjects living in psychiatric institutions, where it was found to have a prevalence of up to 11.4%. Most patients were reported in the literature during the first half of the 20th century. CVG-ID is now a less reported and possibly under-recognized syndrome. Here, we report a patient with CVG-ID that was diagnosed using the novel approach of magnetic resonance imaging and we conduct a systematic review of all patients reported in the last 60 years, discussing the core clinical features of this syndrome. © 2016 Wiley Periodicals, Inc.

Abstract: Gillespie syndrome (GLSP) is a rare congenital disorder characterized by partial aniridia, hypotonia, progressive cerebellar hypoplasia, nonprogressive ataxia, and intellectual disability. All causative variants to date affect the central or the 3'-terminal domains of ITPR1 gene and exhibit autosomal recessive or dominant inheritance pattern. We investigated by exome sequencing the molecular cause of GLSP in a family composed by consanguineous healthy parents, two affected siblings and one healthy son. We found the novel splice site variant c.278_279 + 2delACGT located at the 5'-end of ITPR1. The affected siblings were homozygotes, their parents heterozygous carriers and the variant was absent in the healthy son, indicating a recessive inheritance pattern. The deletion abolished the splice-donor site at exon 5/intron 5 junction, causing the skipping of exon 5 and the generation of a premature STOP codon. The mutation is predicted to result in the synthesis of a 64-amino acids nonfunctional protein. The mutant transcript comprised >96% of ITPR1 mRNA in the affected siblings, indicating that a small amount of wild-type transcript was still present. The novel autosomal recessive mutation here reported is the first variant affecting the ITPR1 N-terminal suppressor domain, thus extending the spectrum of the pathogenetic variants in GLSP and the range of the associated clinical manifestations.

Abstract: Floating-Harbor Syndrome (FHS; OMIM #136140) is an ultra-rare autosomal dominant genetic condition characterized by expressive language delay, short stature with delayed bone mineralization, a triangular face with a prominent nose, and deep-set eyes, and hand anomalies. First reported in 1973, FHS is associated with mutations in the SRCAP gene, which encodes SNF2-related CREBBP activator protein. Mutations in the CREBBP gene cause Rubinstein-Taybi Syndrome (RSTS; OMIM #180849, #613684), another rare disease characterized by broad thumbs and halluces, facial dysmorphisms, short stature, and intellectual disability, which has a phenotypic overlap with FHS. We describe a case of FHS associated with a novel SRCAP mutation and characterized by Perthes disease, a skeletal anomaly described in approximately 3% of patients with RSTS. Thus Perthes disease can be added to the list of clinical features that overlap between FHS and RSTS.

Abstract: CIMBA Consortium et al., PMID: 25849179, [Importance]: Limited information about the relationship between specific mutations in BRCA1 or BRCA2 (BRCA1/2) and cancer risk exists. [Objective]: To identify mutation-specific cancer risks for carriers of BRCA1/2. [Design, Setting, and Participants]: Observational study ofwomen whowere ascertained between 1937 and 2011 (median, 1999) and found to carry disease-associated BRCA1 or BRCA2 mutations. The international sample comprised 19 581 carriers of BRCA1 mutations and 11 900 carriers of BRCA2 mutations from 55 centers in 33 countries on 6 continents.We estimated hazard ratios for breast and ovarian cancer based on mutation type, function, and nucleotide position.We also estimated RHR, the ratio of breast vs ovarian cancer hazard ratios. A value of RHR greater than 1 indicated elevated breast cancer risk; a value of RHR less than 1 indicated elevated ovarian cancer risk. [Exposures]: Mutations of BRCA1 or BRCA2. [Main Outcomes and Measures]: Breast and ovarian cancer risks. [Results]: Among BRCA1 mutation carriers, 9052 women (46%) were diagnosed with breast cancer, 2317 (12%) with ovarian cancer, 1041 (5%) with breast and ovarian cancer, and 7171 (37%) without cancer. Among BRCA2 mutation carriers, 6180 women (52%) were diagnosed with breast cancer, 682 (6%) with ovarian cancer, 272 (2%) with breast and ovarian cancer, and 4766 (40%) without cancer. In BRCA1, we identified 3 breast cancer cluster regions (BCCRs) located at c.179 to c.505 (BCCR1; RHR = 1.46; 95%CI, 1.22-1.74; P = 2 × 10-6), c.4328 to c.4945 (BCCR2; RHR = 1.34; 95%CI, 1.01-1.78; P = .04), and c. 5261 to c.5563 (BCCR2', RHR = 1.38; 95%CI, 1.22-1.55; P = 6 × 10-9).We also identified an ovarian cancer cluster region (OCCR) from c.1380 to c.4062 (approximately exon 11) with RHR = 0.62 (95%CI, 0.56-0.70; P = 9 × 10-17). In BRCA2, we observed multiple BCCRs spanning c.1 to c.596 (BCCR1; RHR = 1.71; 95%CI, 1.06-2.78; P = .03), c.772 to c.1806 (BCCR1'; RHR = 1.63; 95%CI, 1.10-2.40; P = .01), and c.7394 to c.8904 (BCCR2; RHR = 2.31; 95%CI, 1.69-3.16; P = .00002).We also identified 3 OCCRs: the first (OCCR1) spanned c.3249 to c.5681 that was adjacent to c.5946delT (6174delT; RHR = 0.51; 95%CI, 0.44-0.60; P = 6 × 10-17). The second OCCR spanned c.6645 to c.7471 (OCCR2; RHR = 0.57; 95%CI, 0.41-0.80; P = .001). Mutations conferring nonsense-mediated decay were associated with differential breast or ovarian cancer risks and an earlier age of breast cancer diagnosis for both BRCA1 and BRCA2 mutation carriers. [Conclusions and Relevance]: Breast and ovarian cancer risks varied by type and location of BRCA1/2 mutations. With appropriate validation, these data may have implications for risk assessment and cancer prevention decision making for carriers of BRCA1 and BRCA2 mutations., Dr Antoniou and the CIMBA data management are funded by Cancer Research UK.

Abstract: Neurofibromatosis type 1 (NF1) is an hereditary disorder characterized by abnormal proliferation of multiple tissues of neural crest origin, and presents mainly with multiple cafe-au-lait macules, axillary freckling and neurofibromas. Choroidal involvement in NF1 patients has been studied, thanks to the development of non-invasive tools such as infrared monochromatic light during fundus examination, which showed bright patchy lesions consistent with choroidal nodules. Choroidal abnormalities identified with near-infrared reflectance have reported with a frequency of up to 100% in NF1, and have been recently been proposed as a novel diagnostic criterion for NF1. Legius syndrome can be clinically indistinguishable from NF1 and results in a small percentage of individuals being misdiagnosed. We investigated the presence of choroidal abnormalities in Legius syndrome to determine their specificity to NF1 and their potential usefulness as a novel diagnostic criterion for NF1. We examined the fundus of 16 eyes by confocal scanning laser ophthalmoscopy with infrared monochromatic light in eight patients with molecularly confirmed Legius syndrome. No abnormalities were observed, confirming the diagnostic value of choroidal abnormalities for the diagnosis of NF1.

Abstract: In order to evaluate the serum anti-skin autoantibodies and cytokine concentrations in patients with different epidermolysis bullosa (EB) types and severity, 42 EB patients and 38 controls were enrolled. Serum anti-skin antibodies were significantly higher in the patients than in the controls (p = 0.008, p < 0.001, p < 0.001, p < 0.001 and p < 0.001 for desmoglein 1 (DSG1) desmoglein 3 (DSG3), bullous pemphigoid 180 (BP180), BP230 and type VII collagen (COL7), respectively). The same trend was observed for interleukin (IL)-1β, IL-2, IL-6, IL-10, tumor necrosis factor-β, and interferon-γ (p < 0.001, p < 0.001, p < 0.001, p = 0.008, p < 0.001 and p = 0.002, respectively). Increases in anti-skin antibodies and cytokine concentrations were higher in patients with recessive dystrophic EB than in those with different types of EB, in generalized cases than in localized ones, and in patients with higher Birmingham Epidermolysis Bullosa Severity (BEBS) scores than in those with a lower score. The BEBS score was directly correlated with BP180, BP230, COL7 (p = 0.015, p = 0.008 and p < 0.001, respectively) and IL-6 (p = 0.03), whereas IL-6 appeared significantly associated with DSG1, DSG3, BP180, BP230 and COL7 (p = 0.015, p = 0.023, p = 0.023, p = 0.015 and p = 0.005, respectively). This study showed that autoimmunity and inflammatory responses are frequently activated in EB, mainly in severe forms, suggesting the use of immunosuppressive drugs or biologicals that are active against pro-inflammatory cytokines to reduce clinical signs and symptoms of disease.

Abstract: Background BRCA mutation screening is frequently offered on the basis of the fulfillment of empirical selection criteria, thought to be indicative of a genetic predisposition to breast/ovarian cancer (BrCa/OvCa). This study aimed to evaluate, in a large cohort of BrCa/OvCa families, the mutation detection rate (DR) associated with specific clinical features and the relative performance of the employed selection criteria. Methods BRCA gene analysis was performed on 1854 family probands. The Fisher exact test was used to compare the DRs associated with different clinical features. In a subset of families fulfilling only mutually exclusive criteria, odds ratios and 95% CI were estimated to test the relative effectiveness of each criterion. Results The overall DR was 29.3%. Among BrCa-only families, the DRs were significantly higher in the presence of early-onset compared with late-onset cases, and of bilateral compared with unilateral cases. In families with bilateral cases, ages at diagnosis of both the first and second tumour were significantly lower in mutation carriers. In families fulfilling mutually exclusive criteria, OvCa was the best predictor of BRCA mutations, with DRs (range: 31.8%–80.0%) significantly higher compared with the other criteria. Conversely, isolated early-onset BrCa and three or more late-onset BrCa displayed significantly lower predictive values (7.9% and 7.2%, respectively). Conclusions The observed estimates, albeit confirming a DR above 10% for most of the considered criteria, highlighted some relevant differences among them. Such differences should be taken into account in the identification of patients who might benefit from genetic counselling and subsequent testing.

Abstract: Ovarian Cancer Association Consortium, Breast Cancer Association Consortium, and Consortium of Modifiers of BRCA1 and BRCA2: et al., [Objective]: Clinical genetic testing is commercially available for rs61764370, an inherited variant residing in a KRAS 3' UTR microRNA binding site, based on suggested associations with increased ovarian and breast cancer risk as well as with survival time. However, prior studies, emphasizing particular subgroups, were relatively small. Therefore, we comprehensively evaluated ovarian and breast cancer risks as well as clinical outcome associated with rs61764370. [Methods]: Centralized genotyping and analysis were performed for 140,012 women enrolled in the Ovarian Cancer Association Consortium (15,357 ovarian cancer patients; 30,816 controls), the Breast Cancer Association Consortium (33,530 breast cancer patients; 37,640 controls), and the Consortium of Modifiers of BRCA1 and BRCA2 (14,765 BRCA1 and 7904 BRCA2 mutation carriers). [Results]: We found no association with risk of ovarian cancer (OR = 0.99, 95% CI 0.94-1.04, p = 0.74) or breast cancer (OR = 0.98, 95% CI 0.94-1.01, p = 0.19) and results were consistent among mutation carriers (BRCA1, ovarian cancer HR = 1.09, 95% CI 0.97-1.23, p = 0.14, breast cancer HR = 1.04, 95% CI 0.97-1.12, p = 0.27; BRCA2, ovarian cancer HR = 0.89, 95% CI 0.71-1.13, p = 0.34, breast cancer HR = 1.06, 95% CI 0.94-1.19, p = 0.35). Null results were also obtained for associations with overall survival following ovarian cancer (HR = 0.94, 95% CI 0.83-1.07, p = 0.38), breast cancer (HR = 0.96, 95% CI 0.87-1.06, p = 0.38), and all other previously-reported associations. [Conclusions]: rs61764370 is not associated with risk of ovarian or breast cancer nor with clinical outcome for patients with these cancers. Therefore, genotyping this variant has no clinical utility related to the prediction or management of these cancers., The COGS project is funded through a European Commission's Seventh Framework Programme grant (agreement number 223175 — HEALTH-F2-2009-223175).

Abstract: Background: A recent association study identified a common variant (rs9790517) at 4q24 to be associated with breast cancer risk. Independent association signals and potential functional variants in this locus have not been explored. Methods: We conducted a fine-mapping analysis in 55,540 breast cancer cases and 51,168 controls from the Breast Cancer Association Consortium. Results: Conditional analyses identified two independent association signals among women of European ancestry, represented by rs9790517 [conditional P = 2.51 × 10−4; OR, 1.04; 95% confidence interval (CI), 1.02–1.07] and rs77928427 (P = 1.86 × 10−4; OR, 1.04; 95% CI, 1.02–1.07). Functional annotation using data from the Encyclopedia of DNA Elements (ENCODE) project revealed two putative functional variants, rs62331150 and rs73838678 in linkage disequilibrium (LD) with rs9790517 (r2 ≥ 0.90) residing in the active promoter or enhancer, respectively, of the nearest gene, TET2. Both variants are located in DNase I hypersensitivity and transcription factor–binding sites. Using data from both The Cancer Genome Atlas (TCGA) and Molecular Taxonomy of Breast Cancer International Consortium (METABRIC), we showed that rs62331150 was associated with level of expression of TET2 in breast normal and tumor tissue. Conclusion: Our study identified two independent association signals at 4q24 in relation to breast cancer risk and suggested that observed association in this locus may be mediated through the regulation of TET2. Impact: Fine-mapping study with large sample size warranted for identification of independent loci for breast cancer risk. Cancer Epidemiol Biomarkers Prev; 24(11); 1680–91. ©2015 AACR.

Abstract: The chromosomal passenger complex (CPC) plays a pivotal role in the regulation of cell division. Therefore, inherited CPC variability could influence tumor development. The present candidate gene approach investigates the relationship between single nucleotide polymorphisms (SNPs) in genes encoding key CPC components and breast cancer risk. Fifteen SNPs in four CPC genes (INCENP, AURKB, BIRC5 and CDCA8) were genotyped in 88 911 European women from 39 case-control studies of the Breast Cancer Association Consortium. Possible associations were investigated in fixedeffects meta-analyses. The synonymous SNP rs1675126 in exon 7 of INCENP was associated with overall breast cancer risk per A allele odds ratio (OR) 0.95, 95% confidence interval (CI) 0.92-0.98, P = 0.007 and particularly with estrogen receptor (ER)-negative breast tumors (per A allele OR 0.89, 95% CI 0.83-0.95, P = 0.0005). SNPs not directly genotyped were imputed based on 1000 Genomes. The SNPs rs1047739 in the 3' untranslated region and rs144045115 downstream of INCENP showed the strongest association signals for overall (per T allele OR 1.03, 95% CI 1.00-1.06, P = 0.0009) and ER-negative breast cancer risk (per A allele OR 1.06, 95% CI 1.02-1.10, P = 0.0002). Two genotyped SNPs in BIRC5 were associated with familial breast cancer risk (top SNP rs2071214: per G allele OR 1.12, 95% CI 1.04-1.21, P = 0.002). The data suggest that INCENP in the CPC pathway contributes to ER-negative breast cancer susceptibility in the European population. In spite of a modest contribution of CPC-inherited variants to the total burden of sporadic and familial breast cancer, their potential as novel targets for breast cancer treatment should be further investigated.

Abstract: Introduction The distribution of histopathological features of invasive breast tumors in BRCA1 or BRCA2 germline mutation carriers differs from that of individuals with no known mutation. Histopathological features thus have utility for mutation prediction, including statistical modeling to assess pathogenicity of BRCA1 or BRCA2 variants of uncertain clinical significance. We analyzed large pathology datasets accrued by the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) and the Breast Cancer Association Consortium (BCAC) to reassess histopathological predictors of BRCA1 and BRCA2 mutation status, and provide robust likelihood ratio (LR) estimates for statistical modeling. Methods Selection criteria for study/center inclusion were estrogen receptor (ER) status or grade data available for invasive breast cancer diagnosed younger than 70 years. The dataset included 4,477 BRCA1 mutation carriers, 2,565 BRCA2 mutation carriers, and 47,565 BCAC breast cancer cases. Country-stratified estimates of the likelihood of mutation status by histopathological markers were derived using a Mantel-Haenszel approach. Results ER-positive phenotype negatively predicted BRCA1 mutation status, irrespective of grade (LRs from 0.08 to 0.90). ER-negative grade 3 histopathology was more predictive of positive BRCA1 mutation status in women 50 years or older (LR = 4.13 (3.70 to 4.62)) versus younger than 50 years (LR = 3.16 (2.96 to 3.37)). For BRCA2, ER-positive grade 3 phenotype modestly predicted positive mutation status irrespective of age (LR = 1.7-fold), whereas ER-negative grade 3 features modestly predicted positive mutation status at 50 years or older (LR = 1.54 (1.27 to 1.88)). Triple-negative tumor status was highly predictive of BRCA1 mutation status for women younger than 50 years (LR = 3.73 (3.43 to 4.05)) and 50 years or older (LR = 4.41 (3.86 to 5.04)), and modestly predictive of positive BRCA2 mutation status in women 50 years or older (LR = 1.79 (1.42 to 2.24)). Conclusions These results refine likelihood-ratio estimates for predicting BRCA1 and BRCA2 mutation status by using commonly measured histopathological features. Age at diagnosis is an important variable for most analyses, and grade is more informative than ER status for BRCA2 mutation carrier prediction. The estimates will improve BRCA1 and BRCA2 variant classification and inform patient mutation testing and clinical management.

Abstract: Purpose:Monoallelic germ-line deleterious mutations of PALB2 (partner and localizer of BRCA2) are associated with breast cancer risk and have been found in several populations, with carrier frequencies of ∼1-2%. Initially, these mutations were considered to have moderate penetrance, but accumulating evidence now indicates that they are associated with much higher risk.Methods:In this study, we sequenced the PALB2 coding regions unlinked to BRCA (breast cancer) genes in 575 probands from Italian breast cancer families recruited in Milan.Results:We found 12 carriers (2.1%) of deleterious mutations, and none of the mutations was found in 784 controls collected in Milan. One of these mutations, the c.1027C>T (p.Gln343X), was found to be recurrent in the province of Bergamo in northern Italy, being detected in 6/113 (5.3%) familial breast cancer cases and 2/477 (0.4%) controls recruited in this area (Fisher's exact test: P < 0.01).Conclusions:Our data provide confirmatory findings that, in the Italian population also, deleterious mutations of PALB2 are relatively frequent predisposing factors for breast cancer and may be associated with high risk of the disease.Genet Med 16 9, 688-694.

Abstract: Williams syndrome (WS) is a rare, multisystemic genomic disorder showing a high prevalence of impaired glucose metabolism in adulthood. The reason for this association is unknown, though hemizygosity for genes mapping to the WS chromosome region has been implicated. Twenty-two Italian young adults with WS (13 females, 9 males) were studied. A 75 g oral glucose tolerance test (OGTT) was performed and β-cell function was estimated with Homeostasis Model Assessment (HOMA)-B%, Insulinogenic Index, and corrected insulin response whereas insulin sensitivity was assessed with HOMA-Insulin Resistance Index, Quantitative Insulin Check Index, and composite Insulin Sensitivity Index. One patient had known diabetes mellitus (DM), whereas impaired glucose tolerance (IGT) was diagnosed in 12 patients and DM in one (63.6% prevalence of impaired glucose metabolism). IGT patients were more insulin resistant than those with normal glucose tolerance (NGT), whereas β-cell function was unchanged or increased. Islet autoimmunity was absent. Logistic regression showed that impaired glucose metabolism was not associated with age, body mass index (BMI), or family history of DM. β-cell function, insulin sensitivity, and post-load insulin levels did not differ between WS patients with NGT and healthy controls comparable for gender, age, and BMI, though WS-NGT patients had higher post-load glucose values. These data confirm the high prevalence of impaired glucose metabolism in WS young adults, thus suggesting the need for screening these patients with OGTT. IGT is associated with reduced insulin sensitivity, but not with impaired β-cell function, islet autoimmunity, and traditional risk factors for type 2 DM.
