Abstract

The missense mutation p.R406W in microtubule-associated protein tau leads to frontotemporal lobar degeneration with an amnestic, Alzheimer's disease-like phenotype with an autosomal dominant pattern of inheritance. In 2003, we described the pedigree of a Belgian family, labelled ADG, with 28 p.R406W patients. Over 18 years follow-up, we extended the family with 10 p.R406W carriers and provided an in-depth clinical description of the patients. Additionally, genetic screening was used to identify p.R406W carriers in Belgian cohorts of frontotemporal dementia and Alzheimer's disease patients and to calculate p.R406W frequency. In the frontotemporal dementia cohort, we found four p.R406W carriers (n = 647, 0.62%) and three in the Alzheimer's disease cohort (n = 1134, 0.26%). Haplotype sharing analysis showed evidence of a shared haplotype suggesting that they are descendants of a common ancestor. Of the p.R406W patients, we describe characteristics of neuropsychological, imaging and fluid biomarkers as well as neuropathologic examination. Intriguingly, the phenotypic spectrum among the p.R406W patients ranged from typical behavioural variant frontotemporal dementia to clinical Alzheimer's disease, based on CSF biomarker analysis and amyloid PET scan. Heterogeneous overlap syndromes existed in between, with highly common neuropsychiatric symptoms like disinhibition and aggressiveness, which occurred in 100% of frontotemporal dementia and 58% of clinical Alzheimer's disease patients. This was also the case for memory problems, 89% in frontotemporal dementia and 100% in clinical Alzheimer's disease patients. Median age at death was significantly lower in patients with frontotemporal dementia (68 years) compared to clinical Alzheimer's disease patients (79 years), although the sizes of the sub-cohorts are limited and do not allow prognostic predictions. Post-mortem brain analysis of one p.R406W patient with behavioural variant frontotemporal dementia revealed frontotemporal, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

North Carolina macular dystrophy (NCMD) is a rare autosomal-dominant disease affecting macular development. The disease is caused by non-coding single-nucleotide variants (SNVs) in two hotspot regions near PRDM13 and by duplications in two distinct chromosomal loci, overlapping DNase I hypersensitive sites near either PRDM13 or IRX1. To unravel the mechanisms by which these variants cause disease, we first established a genome-wide multi-omics retinal database, RegRet. Integration of UMI-4C profiles we generated on adult human retina then allowed fine-mapping of the interactions of the PRDM13 and IRX1 promoters and the identification of eighteen candidate cis-regulatory elements (cCREs), the activity of which was investigated by luciferase and Xenopus enhancer assays. Next, luciferase assays showed that the non-coding SNVs located in the two hotspot regions of PRDM13 affect cCRE activity, including two NCMD-associated non-coding SNVs that we identified herein. Interestingly, the cCRE containing one of these SNVs was shown to interact with the PRDM13 promoter, demonstrated in vivo activity in Xenopus, and is active at the developmental stage when progenitor cells of the central retina exit mitosis, suggesting that this region is a PRDM13 enhancer. Finally, mining of single-cell transcriptional data of embryonic and adult retina revealed the highest expression of PRDM13 and IRX1 when amacrine cells start to synapse with retinal ganglion cells, supporting the hypothesis that altered PRDM13 or IRX1 expression impairs interactions between these cells during retinogenesis. Overall, this study provides insight into the cis-regulatory mechanisms of NCMD and supports that this condition is a retinal enhanceropathy., This work was supported by grants from Ghent University Special Research Fund (BOF20/GOA/023) (E.D.B., K.V., B.P.L.); Ghent University Hospital Innovation Fund NucleUZ (E.D.B.); JED Foundation (E.D.B.); H2020 Marie Sklodowska-Curie Innovative Training Networks (ITN) StarT (grant No. 813490) (E.D.B., K.V., J.L.G.-S., J.J.T., J.R.M.-M.); EJP RD Solve-RET EJPRD19-234 (E.D.B., P.L.,B.K., C.R., J.L.G.-S., J.J.T., J.R.M.-M.), SNSF grant # 204285 (C.R.), and Foundation Fighting Blindness in Columbia, MD (grant #: BR-GE-1216-0715-CSH).

Abstract

The gene for sclerosteosis has been localized to chromosome 17q12-q21, in the same region as the gene associated with van Buchem disease. The two conditions are clinically similar, although gigantism and hand abnormalities are associated with sclerosteosis but not with van Buchem disease. Evidence suggests allelic status for the two conditions. Dutch ancestry is associated with both conditions.

Abstract

Proteins anchored to the cell surface via glycosylphosphatidylinositol (GPI) play various key roles in the human body, particularly in development and neurogenesis. As such, many developmental disorders are caused by mutations in genes involved in the GPI biosynthesis and remodeling pathway. We describe ten unrelated families with bi-allelic mutations in PIGB, a gene that encodes phosphatidy-linositol glycan class B, which transfers the third mannose to the GPI. Ten different PIGB variants were found in these individuals. Flow cytometric analysis of blood cells and fibroblasts from the affected individuals showed decreased cell surface presence of GPI-anchored proteins. Most of the affected individuals have global developmental and/or intellectual delay, all had seizures, two had polymicrogyria, and four had a peripheral neuropathy. Eight children passed away before four years old. Two of them had a clinical diagnosis of DOORS syndrome (deafness, onychodystrophy, osteodystrophy, mental retardation, and seizures), a condition that includes sensorineural deafness, shortened terminal phalanges with small finger and toenails, intellectual disability, and seizures; this condition overlaps with the severe phenotypes associated with inherited GPI deficiency. Most individuals tested showed elevated alkaline phosphatase, which is a characteristic of the inherited GPI deficiency but not DOORS syndrome. It is notable that two severely affected individuals showed 2-oxoglutaric aciduria, which can be seen in DOORS syndrome, suggesting that severe cases of inherited GPI deficiency and DOORS syndrome might share some molecular pathway disruptions.

Abstract

Background: We identified 13 unrelated index patients carrying the presenilin 1 (PSEN1) missense mutation, p.Cys263Phe in a Flanders‐Belgian cohort of Alzheimer's disease (AD) patients. Seven affected relatives in three different families also carried the PSEN1 p.Cys263Phe mutation (n=20). We aimed to delineate a clinicopathological phenotype of p.Cys263Phe carriers. We compared the p.Cys263Phe genotype–phenotype with that of AD patients carrying autosomal dominant mutations i.e. PSEN1 (n=29), PSEN2 (n=1), and APP (n=5). Methods: Reviewing of medical records of autosomal dominant mutation carriers to obtain clinical and pathological data for defining genotype‐phenotype data. Results: Mean onset age of the p.Cys263Phe carriers is 63.9±5.5 years (range 53‐79), with a disease duration of 7.0±3.5 years (range 4‐13). APOE genotypes have no significant effects on onset age. A positive familial history is present in 92.9% of the carriers. Segregation with disease is present in two families with autosomal dominant inheritance of AD (figure 1). In all carriers the clinical presentation is predominantly amnestic, although 35.7% (5/14) of the patients also show significant frontal symptoms. Structural neuroimaging displays diffuse (sub)cortical atrophy with evident hippocampal atrophy in 26.7% (4/15) of the carriers. In 40.0% (6/15) of the patients we observe severe signs of small vessel disease. Brain perfusion SPECT or fluorodeoxyglucose PET imaging shows bilateral temporoparietal involvement in 57.1% (4/7) of carriers. Cerebrospinal fluid AD biomarkers were analyzed in eight carriers, and all are characteristic for AD. Neuropathological examination in three carriers shows severe levels of hallmark AD lesions combined with pronounced cerebral amyloid angiopathy (CAA) and multiple intracerebral hemorrhages in one patient. Carriers of p.Cys263Phe have a later age at onset (63.9 years) compared to PSEN1 carriers (50.9 years) and other PSEN1, PSEN2 and APP mutation carriers (51.4 years) (figure 2). Conclusion: PSEN1 p.Cys263Phe carriers present with early‐onset familial AD with autosomal dominant co‐segregation. Important is that frontal symptoms are seen in 35.7% of the carrier while neuropathological examination reveals severe levels of AD neuropathology with prominent presence of CAA. The disease onset of PSEN1 p.Cys263Phe carriers is later in comparison with other autosomal dominant gene mutation carriers. [ABSTRACT FROM AUTHOR]

Abstract

Sclerosteosis is a progressive sclerosing bone dysplasia with an autosomal recessive mode of inheritance. Radiologically, it is characterized by a generalized hyperostosis and sclerosis leading to a markedly thickened and sclerotic skull, with mandible, ribs, clavicles and all long bones also being affected. Due to narrowing of the foramina of the cranial nerves, facial nerve palsy, hearing loss and atrophy of the optic nerves can occur. Sclerosteosis is clinically and radiologically very similar to van Buchem disease, mainly differentiated by hand malformations and a large stature in sclerosteosis patients. By linkage analysis in one extended van Buchem family and two consanguineous sclerosteosis families we previously mapped both disease genes to the same chromosomal 17q12-q21 region, supporting the hypothesis that both conditions are caused by mutations in the same gene. After reducing the disease critical region to ~1 Mb, we used the positional cloning strategy to identify the SOST gene, which is mutated in sclerosteosis patients. This new gene encodes a protein with a signal peptide for secretion and a cysteine-knot motif. Two nonsense mutations and one splice site mutation were identified in sclerosteosis patients, but no mutations were found in a fourth sclerosteosis patient nor in the patients from the van Buchem family. As the three disease-causing mutations lead to loss of function of the SOST protein resulting in the formation of massive amounts of normal bone throughout life, the physiological role of SOST is most likely the suppression of bone formation. Therefore, this gene might become an important tool in the development of therapeutic strategies for osteoporosis

Abstract

International audience; KAT6B sequence variants have been identified previously in both patients with the Say-Barber-Biesecker type of blepharophimosis mental retardation syndromes (SBBS) and in the more severe genitopatellar syndrome (GPS). We report on the findings in a previously unreported group of 57 individuals with suggestive features of SBBS or GPS. Likely causative variants have been identified in 34/57 patients and were commonly located in the terminal exons of KAT6B. Of those where parental samples could be tested, all occurred de novo. Thirty out of thirty-four had truncating variants, one had a missense variant and the remaining three had the same synonymous change predicted to affect splicing. Variants in GPS tended to occur more proximally to those in SBBS patients, and genotype/phenotype analysis demonstrated significant clinical overlap between SBBS and GPS. The de novo synonymous change seen in three patients with features of SBBS occurred more proximally in exon 16. Statistical analysis of clinical features demonstrated that KAT6B variant-positive patients were more likely to display hypotonia, feeding difficulties, long thumbs/great toes and dental, thyroid and patella abnormalities than KAT6B variant-negative patients. The few reported patients with KAT6B haploinsufficiency had a much milder phenotype, though with some features overlapping those of SBBS. We report the findings in a previously unreported patient with a deletion of the KAT6B gene to further delineate the haploinsufficiency phenotype. The molecular mechanisms giving rise to the SBBS and GPS phenotypes are discussed.

Abstract

Mutations in the NOG gene give rise to a wide range of clinical phenotypes. Noggin, the protein encoded by this gene is a secreted modulator of multiple pathways involved in both bone and joint development. Proximal symphalangism is commonly observed in patients bearing mutations in this gene, however secondary symptomes are often found including typical facies with hemicylindrical nose with bulbous tip, hyperopia, reduced mobility of multiple joints, hearing loss due to stapes fixation, and recurrent pain from affected joints. With large variation of the phenotype both within and between affected families careful delineation of the genotype-phenotype correlation is needed. In this work we describe a Danish family suffering from SYNS1 due to a novel NOG gene mutation (C230Y). We provide detailed clinical description of the family members presenting rare phenotype of the shoulders shared by affected individuals but no hearing loss, further adding to the phenotypic variability of the syndrome. With these findings we broaden the understanding of NOG-related-symphalangism spectrum disorder.

Abstract

KAT6B sequence variants have been identified previously in both patients with the Say-Barber-Biesecker type of blepharophimosis mental retardation syndromes (SBBS) and in the more severe genitopatellar syndrome (GPS). We report on the findings in a previously unreported group of 57 individuals with suggestive features of SBBS or GPS. Likely causative variants have been identified in 34/57 patients and were commonly located in the terminal exons of KAT6B. Of those where parental samples could be tested, all occurred de novo. Thirty out of thirty-four had truncating variants, one had a missense variant and the remaining three had the same synonymous change predicted to affect splicing. Variants in GPS tended to occur more proximally to those in SBBS patients, and genotype/phenotype analysis demonstrated significant clinical overlap between SBBS and GPS. The de novo synonymous change seen in three patients with features of SBBS occurred more proximally in exon 16. Statistical analysis of clinical features demonstrated that KAT6B variant-positive patients were more likely to display hypotonia, feeding difficulties, long thumbs/great toes and dental, thyroid and patella abnormalities than KAT6B variant-negative patients. The few reported patients with KAT6B haploinsufficiency had a much milder phenotype, though with some features overlapping those of SBBS. We report the findings in a previously unreported patient with a deletion of the KAT6B gene to further delineate the haploinsufficiency phenotype. The molecular mechanisms giving rise to the SBBS and GPS phenotypes are discussed.

Abstract

Despite the high heritability of autism spectrum disorders (ASD), characterized by persistent deficits in social communication and interaction and restricted, repetitive patterns of behavior, interests or activities(1), a genetic diagnosis can be established in only a minority of patients. Known genetic causes include chromosomal aberrations, such as the duplication of the 15q11-13 region, and monogenic causes, as in Rett and fragile- X syndromes. The genetic heterogeneity within ASD is striking, with even the most frequent causes responsible for only 1% of cases at the most. Even with the recent developments in nextgeneration sequencing, for the large majority of cases no molecular diagnosis can be established(2-7). Here, we report ten patients with ASD and other shared clinical characteristics, including intellectual disability and facial dysmorphisms caused by a mutation in ADNP, a transcription factor involved in the SWI/ SNF remodeling complex. We estimate this gene to be mutated in at least 0.17% of ASD cases, making it one of the most frequent ASD- associated genes known to date.
