Abstract

We present a family in which four individuals have been identified with the same likely pathogenic genetic alteration in the PIK3CA gene at the germinal level; specifically, c.1145G>A p.(Arg382Lys) missense type. The index case patient was diagnosed with multinodular goiter and breast cancer at 61 years old. Among the other three carrier relatives: one has been diagnosed with serous cystadenoma of the ovary and a thyroid nodule with no radiological suspicion of malignancy; the other two present multinodular goiter. Additionally, a sister of three of the carriers suffered from an ovarian teratoma, follicular thyroid carcinoma on multinodular goiter, and high-grade serous ovarian carcinoma. No direct mutation study was performed on her as she had died due to ovarian carcinoma. This finding suggests that the PIK3CA gene should be considered in Cowden-like families when no other gene mutations have been found. Furthermore, this report contributes to characterization of the clinical phenotype caused by mutations in PIK3CA, which may be shared with other hereditary breast and ovarian cancer syndromes.

Abstract

Dysfunction of some mitochondrial aminoacyl-tRNA synthetases (encoded by the KARS1, HARS2, LARS2 and NARS2 genes) results in a great variety of phenotypes ranging from non-syndromic hearing impairment (NSHI) to very complex syndromes, with a predominance of neurological signs. The diversity of roles that are played by these moonlighting enzymes and the fact that most pathogenic variants are missense and affect different domains of these proteins in diverse compound heterozygous combinations make it difficult to establish genotype–phenotype correlations. We used a targeted gene-sequencing panel to investigate the presence of pathogenic variants in those four genes in cohorts of 175 Spanish and 18 Colombian familial cases with non-DFNB1 autosomal recessive NSHI. Disease-associated variants were found in five cases. Five mutations were novel as follows: c.766C>T in KARS1, c.475C>T, c.728A>C and c.1012G>A in HARS2, and c.795A>G in LARS2. We provide audiograms from patients at different ages to document the evolution of the hearing loss, which is mostly prelingual and progresses from moderate/severe to profound, the middle frequencies being more severely affected. No additional clinical sign was observed in any affected subject. Our results confirm the involvement of KARS1 in DFNB89 NSHI, for which until now there was limited evidence. [ABSTRACT FROM AUTHOR]

Abstract

Las hipoacusias neurosensoriales no sindrómicas son el trastorno sensorial más común y presentan una alta heterogeneidad genética. La identificación de nuevos genes y variantes asociados a hipoacusia avanza a un ritmo muy rápido, lo que hace que el uso de herramientas de secuenciación masiva sea esencial para realizar un diagnóstico genético. En este trabajo, hemos utilizado OTO-NGS-panel V2, un panel de secuenciación masiva diseñado por nuestro grupo que contiene 117 genes asociados a hipoacusias para estudiar el espectro mutacional de las hipoacusias no sindrómicas de herencia autosómica dominante en la población española. OTO-NGS-panel V2 fue validado para la identificación de mutaciones puntuales, pequeñas inserciones y deleciones y variaciones del número de copias. Con esta herramienta, se analizaron 108 familias con hipoacusia no sindrómica e identificamos la variante causal en 39 casos, lo que constituye una tasa diagnóstica del 36,11%. Los genes con mayor prevalencia son WFS1 (7,41 %), seguido de MYO7A (5,56 %), MYO6 (4,63 %), TECTA (2,78 %) y ACTG1 (2,78 %). Para determinar la causa genética de la sordera en los casos que permanecieron sin diagnosticar tras el análisis con OTO-NGS-panel V2, diseñamos un panel de genes candidatos, que incluye genes asociados a sordera en ratón pero sin mutaciones reportadas en humanos hasta la fecha. Se identificaron variantes candidatas en los genes XIRP2, USP31, PLS1 y KCNK5..., Non-syndromic sensorineural hearing loss (SNHL) is the most common sensory disorder, and it presents a high genetic heterogeneity. New genes and variants associated with hearing loss are described at a very rapid pace, making the use of next-generation sequencing (NGS) approaches essential to undertake a genetic diagnosis.We have used OTO-NGS-panel V2, a custom-designed NGS panel containing 117 genes associated with hearing loss to study the mutational spectrum of autosomal dominant non-syndromic hearing loss in the Spanish clinical population. OTO-NGS-panel V2 was validated for the identification of single nucleotide variants (SNVs), small insertions and deletions (Indels) and copy number variations (CNVs), and 108 Spanish families with autosomal dominant non-syndromic hearing loss (ADNSHL) were analysed. We identified the causative variant in 39 cases, constituting a diagnostic rate of 36.11%. The genes with the highest prevalence are WFS1 (7.41%) followed by MYO7A (5.56%), MYO6 (4.63%), TECTA (2.78%) and ACTG1 (2.78%). To identify the genetic cause of deafness in the cases that remained undiagnosed upon analysis with OTO-NGS-panel V2, we designed a candidate gene panel, including genes known to cause deafness in mice but with no human mutations reported so far. Candidate variants were found in the genes XIRP2, USP31, PLS1 and KCNK5...

Abstract

Coenzyme A (CoA) is an essential cofactor involved in a range of metabolic pathways including the activation of long-chain fatty acids for catabolism. Cells synthesize CoA de novo from vitamin B5 (pantothenate) via a pathway strongly conserved across prokaryotes and eukaryotes. In humans, it involves five enzymatic steps catalyzed by four enzymes: pantothenate kinase (PANK [isoforms 1-4]), 4'-phosphopantothenoylcysteine synthetase (PPCS), phosphopantothenoylcysteine decarboxylase (PPCDC), and CoA synthase (COASY). To date, inborn errors of metabolism associated with all of these genes, except PPCDC, have been described, two related to neurodegeneration with brain iron accumulation (NBIA), and one associated with a cardiac phenotype. This paper reports another defect in this pathway (detected in two sisters), associated with a fatal cardiac phenotype, caused by biallelic variants (p.Thr53Pro and p.Ala95Val) of PPCDC. PPCDC enzyme (EC 4.1.1.36) catalyzes the decarboxylation of 4'-phosphopantothenoylcysteine to 4'-phosphopantetheine in CoA biosynthesis. The variants p.Thr53Pro and p.Ala95Val affect residues highly conserved across different species; p.Thr53Pro is involved in the binding of flavin mononucleotide, and p.Ala95Val is likely a destabilizing mutation. Patient-derived fibroblasts showed an absence of PPCDC protein, and nearly 50% reductions in CoA levels. The cells showed clear energy deficiency problems, with defects in mitochondrial respiration, and mostly glycolytic ATP synthesis. Functional studies performed in yeast suggest these mutations to be functionally relevant. In summary, this work describes a new, ultra-rare, severe inborn error of metabolism due to pathogenic variants of PPCDC.

Abstract

Clustered regularly interspaced short palindromic repeats (CRISPR)-associated Cas9 is an effector protein that targets invading DNA and plays a major role in the prokaryotic adaptive immune system. Although Streptococcus pyogenes CRISPR–Cas9 has been widely studied and repurposed for applications including genome editing, its origin and evolution are poorly understood. Here, we investigate the evolution of Cas9 from resurrected ancient nucleases (anCas) in extinct firmicutes species that last lived 2.6 billion years before the present. We demonstrate that these ancient forms were much more flexible in their guide RNA and protospacer-adjacent motif requirements compared with modern-day Cas9 enzymes. Furthermore, anCas portrays a gradual palaeoenzymatic adaptation from nickase to double-strand break activity, exhibits high levels of activity with both single-stranded DNA and single-stranded RNA targets and is capable of editing activity in human cells. Prediction and characterization of anCas with a resurrected protein approach uncovers an evolutionary trajectory leading to functionally flexible ancient enzymes.

Abstract

Non-syndromic hearing impairment (NSHI) is a very heterogeneous genetic condition, involving over 130 genes. Mutations in GJB2, encoding connexin-26, are a major cause of NSHI (the DFNB1 type), but few other genes have significant epidemiological contributions. Mutations in the STRC gene result in the DFNB16 type of autosomal recessive NSHI, a common cause of moderate hearing loss. STRC is located in a tandem duplicated region that includes the STRCP1 pseudogene, and so it is prone to rearrangements causing structural variations. Firstly, we screened a cohort of 122 Spanish familial cases of non-DFNB1 NSHI with at least two affected siblings and unaffected parents, and with different degrees of hearing loss (mild to profound). Secondly, we screened a cohort of 64 Spanish sporadic non-DFNB1 cases, and a cohort of 35 Argentinean non-DFNB1 cases, all of them with moderate hearing loss. Amplification of marker D15S784, massively parallel DNA sequencing, multiplex ligation-dependent probe amplification and long-range gene-specific PCR followed by Sanger sequencing were used to search and confirm single-nucleotide variants (SNVs) and deletions involving STRC. Causative variants were found in 13 Spanish familial cases (10.7%), 5 Spanish simplex cases (7.8%) and 2 Argentinean cases (5.7%). In all, 34 deleted alleles and 6 SNVs, 5 of which are novel. All affected subjects had moderate hearing impairment. Our results further support this strong genotype–phenotype correlation and highlight the significant contribution of STRC mutations to moderate NSHI in the Spanish population. [ABSTRACT FROM AUTHOR]

Abstract

Pathogenic variants in the PJVK gene cause the DFNB59 type of autosomal recessive non-syndromic hearing impairment (AR-NSHI). Phenotypes are not homogeneous, as a few subjects show auditory neuropathy spectrum disorder (ANSD), while others show cochlear hearing loss. The numbers of reported cases and pathogenic variants are still small to establish accurate genotype-phenotype correlations. We investigated a cohort of 77 Spanish familial cases of AR-NSHI, in whom DFNB1 had been excluded, and a cohort of 84 simplex cases with isolated ANSD in whom OTOF variants had been excluded. All seven exons and exon-intron boundaries of the PJVK gene were sequenced. We report three novel DFNB59 cases, one from the AR-NSHI cohort and two from the ANSD cohort, with stable, severe to profound NSHI. Two of the subjects received unilateral cochlear implantation, with apparent good outcomes. Our study expands the spectrum of PJVK mutations, as we report four novel pathogenic variants: p.Leu224Arg, p.His294Ilefs*43, p.His294Asp and p.Phe317Serfs*20. We review the reported cases of DFNB59, summarize the clinical features of this rare subtype of AR-NSHI and discuss the involvement of PJVK in ANSD.

Abstract

The knowledge of the genetic variability of the local population is of utmost importance in personalized medicine and has been revealed as a critical factor for the discovery of new disease variants. Here, we present the Collaborative Spanish Variability Server (CSVS), which currently contains more than 2000 genomes and exomes of unrelated Spanish individuals. This database has been generated in a collaborative crowdsourcing effort collecting sequencing data produced by local genomic projects and for other purposes. Sequences have been grouped by ICD10 upper categories. A web interface allows querying the database removing one or more ICD10 categories. In this way, aggregated counts of allele frequencies of the pseudo-control Spanish population can be obtained for diseases belonging to the category removed. Interestingly, in addition to pseudo-control studies, some population studies can be made, as, for example, prevalence of pharmacogenomic variants, etc. In addition, this genomic data has been used to define the first Spanish Genome Reference Panel (SGRP1.0) for imputation. This is the first local repository of variability entirely produced by a crowdsourcing effort and constitutes an example for future initiatives to characterize local variability worldwide. CSVS is also part of the GA4GH Beacon network. CSVS can be accessed at: http://csvs.babelomics.org/.

Abstract

T cells recognize antigens via their cell surface TCR and are classified as either αβ or γδ depending on the variable chains in their TCR, α and βor γ and δ, respectively. Both αβ and γδ TCRs also contain several invariant chains, including CD3δ, which support surface TCR expression and transduce the TCR signal. Mutations in variable chains would be expected to affect a single T cell lineage, while mutations in the invariant chains would affect all T cells. Consistent with this, all CD3δ-deficient patients described to date showed a complete block in T cell development. However, CD3δ-KO mice have an αβ T cell-specific defect. Here, we report 2 unrelated cases of SCID with a selective block in αβ but not in γδ Tcell development, associated with a new splicing mutation in the CD3D gene. The patients' T cells showed reduced CD3D transcripts, CD3δ proteins, surface TCR, and early TCR signaling. Their lymph nodes showed severe T cell depletion, recent thymus emigrants in peripheral blood were strongly decreased, and the scant αβ T cells were oligoclonal. T cell-dependent B cell functions were also impaired, despite the presence of normal B cell numbers. Strikingly, despite the specific loss of αβ T cells, surface TCR expression was more reduced in γδ than in αβ T cells. Analysis of individuals with this CD3D mutation thus demonstrates the contrasting CD3δ requirements for αβ versus γδ Tcell development and TCR expression in humans and highlights the diagnostic and clinical relevance of studying both TCR isotypes when a T cell defect is suspected., Introduction T lymphocytes recognize antigens by means of a cell surface complex termed the TCR. The TCR contains 2 variable chains to bind antigens and several invariant chains to support [...]

Abstract

The knowledge of the genetic variability of the local population is of utmost importance in personalized medicine and has been revealed as a critical factor for the discovery of new disease variants. Here, we present the Collaborative Spanish Variability Server (CSVS), which currently contains more than 2000 genomes and exomes of unrelated Spanish individuals. This database has been generated in a collaborative crowdsourcing effort collecting sequencing data produced by local genomic projects and for other purposes. Sequences have been grouped by ICD10 upper categories. A web interface allows querying the database removing one or more ICD10 categories. In this way, aggregated counts of allele frequencies of the pseudo-control Spanish population can be obtained for diseases belonging to the category removed. Interestingly, in addition to pseudo-control studies, some population studies can be made, as, for example, prevalence of pharmacogenomic variants, etc. In addition, this genomic data has been used to define the first Spanish Genome Reference Panel (SGRP1.0) for imputation. This is the first local repository of variability entirely produced by a crowdsourcing effort and constitutes an example for future initiatives to characterize local variabilityworldwide. CSVS is also part of the GA4GH Beacon network., Spanish Ministry of Economy and Competitiveness SAF2017-88908-R PT17/0009/0006 PI19/00321 CIBERER ACCI-06/07/0036 PI14-948 PI171659, Regional Government of Madrid, RAREGenomicsCM B2017/BMD3721 B2017/BMD-3721, European Union (EU), European Union (EU) 676559, University Chair UAM-IIS-FJD of Genomic Medicine, Ramon Areces Foundation

Abstract

Resumen del póster presentado al 42nd Congress of the Spanish Society of Biochemistry and Molecular Biology (SEBBM), celebrado en Madrid del 16 al 19 de julio de 2019., La deficiencia humana del factor de crecimiento similar a la insulina tipo 1 (IGF-1) causa una enfermedad rara (ORPHA 73272) que cursa con retraso en el crecimiento, microcefalia y sordera neurosensorial. El modelo murino deficiente en Igf1 reproduce el mismo síndrome y presenta una incorrecta diferenciación neuronal del ganglio auditivo acompañada de apoptosis temprana de las neuronas auditivas. El estudio del papel protector que ejerce el IGF-1 frente a la pérdida auditiva es complicado por la heterogeneidad celular de la cóclea y la limitación de los modelos experimentales disponibles. Como consecuencia, se ha generado un modelo celular de la enfermedad humana en la línea de neuroblastoma murino Neuro2a mediante edición génica con CRISPR/Cas9. Dicho modelo reproduce la deleción parcial del exón 3 del gen Igf1 murino descrita como causante de pérdida auditiva en el hombre. Para la edición génica se transfectó el complejo crRNA:tracrRNA:Cas9 en forma de ribonucleoproteína y se comprobó su incorporación en las células mediante microscopía detectando el tracrRNA marcado fluorescentemente. La presencia de mutaciones se evaluó mediante Surveyor y se seleccionaron las células mutadas tras clonación por dilución límite. La edición del gen Igf1 se comprobó por PCR en 56 clones y 5 de ellos se secuenciaron mediante el méetodo Sanger, confirmándose la deleción parcial de Igf1 en dos de los clones. Para el resto se emplearía la herramienta Mosaic Finder, desarrollada in-house, que permite analizar la multiplicidad alélica generada tras la edición genética mediante next-generation sequencing (NGS) y posterior análisis bioinformático. Finalmente, se ha iniciado un estudio del estado neuroinflamatorio de los clones secuenciados y de su respuesta a distintos estímulos pro-inflamatorios, que puede contribuir a desvelar algunos mecanismos moleculares asociados a la deficiencia crónica de IGF-1., Agradecimientos: ACCI2016 (ER16P5AC7091); ACCI2017 (ER17P5AC7611) y ACCI2018 (ER19P5AC761).

Abstract

Particular genes may be associated with increased risk and severity of systemic lupus erythematosus (SLE) in Spanish people. SLE is an autoimmune disease. Researchers in Spain compared genetic profiles of 85 people with SLE and 186 healthy volunteers. Particular human leukocyte antigen (HLA) genes were more common in SLE patients, and associated with kidney damage from the disease. The genes which related to SLE in Spanish patients were different than those associated with the disease in other ethnic groups.

Abstract

Linkage analysis combined with whole-exome sequencing in a large family with congenital and stable non-syndromic unilateral and asymmetric hearing loss (NS-UHL/AHL) revealed a heterozygous truncating mutation, c.286_303delinsT (p.Ser96Ter), in KITLG. This mutation co-segregated with NS-UHL/AHL as a dominant trait with reduced penetrance. By screening a panel of probands with NS-UHL/AHL, we found an additional mutation, c.200_202del (p.His67_Cys68delinsArg). In vitro studies revealed that the p.His67_Cys68delinsArg transmembrane isoform of KITLG is not detectable at the cell membrane, supporting pathogenicity. KITLG encodes a ligand for the KIT receptor. Also, KITLG-KIT signaling and MITF are suggested to mutually interact in melanocyte development. Because mutations in MITF are causative of Waardenburg syndrome type 2 (WS2), we screened KITLG in suspected WS2-affected probands. A heterozygous missense mutation, c.310C>G (p.Leu104Val), that segregated with WS2 was identified in a small family. In vitro studies revealed that the p.Leu104Val transmembrane isoform of KITLG is located at the cell membrane, as is wild-type KITLG. However, in culture media of transfected cells, the p.Leu104Val soluble isoform of KITLG was reduced, and no soluble p.His67_Cys68delinsArg and p.Ser96Ter KITLG could be detected. These data suggest that mutations in KITLG associated with NS-UHL/AHL have a loss-of-function effect. We speculate that the mechanism of the mutation underlying WS2 and leading to membrane incorporation and reduced secretion of KITLG occurs via a dominant-negative or gain-of-function effect. Our study unveils different phenotypes associated with KITLG, previously associated with pigmentation abnormalities, and will thereby improve the genetic counseling given to individuals with KITLG variants.

Abstract

Mutations in the potassium channel gene KCNQ4 underlie DFNA2, a subtype of autosomal dominant progressive, high-frequency hearing loss. Based on a phenotype-guided mutational screening we have identified a novel mutation c.886G>A, leading to the p.G296S substitution in the pore region of KCNQ4 channel. The possible impact of this mutation on total KCNQ4 protein expression, relative surface expression and channel function was investigated. When the G296S mutant was expressed in Xenopus oocytes, electrophysiological recordings did not show voltage-activated K+ currents. The p.G296S mutation impaired KCNQ4 channel activity in two manners. It greatly reduced surface expression and, secondarily, abolished channel function. The deficient expression at the cell surface membrane was further confirmed in non-permeabilized NIH-3T3 cells transfected with the mutant KCNQ4 tagged with the hemagglutinin epitope in the extracellular S1-S2 linker. Co-expression of mutant and wild type KCNQ4 in oocytes was performed to mimic the heterozygous condition of the p.G296S mutation in the patients. The results showed that the G296S mutant exerts a strong dominant-negative effect on potassium currents by reducing the wild type KCNQ4 channel expression at the cell surface. This is the first study to identify a trafficking-dependent dominant mechanism for the loss of KCNQ4 channel function in DFNA2. © Springer-Verlag 2007.

Abstract

Labyrinthine aplasia, microtia, and microdontia (LAMM) is an autosomal recessive condition causing profound congenital deafness, complete absence of inner ear structures (usually Michel's aplasia), microtia (usually type 1) and microdontia. To date, several families have been described with this condition and a number of mutations has been reported. We report on eight further cases of LAMM syndrome including three novel mutations, c. 173T>C p.L58P; c. 284G>A p.(Arg95Gln) and c.325_327delinsA p.(Glu109Thrfs*18). Congenital deafness was the primary presenting feature in all affected individuals and consanguinity in all but two families. We compare the features in our patients to those previously reported in LAMM, and describe a milder, asymmetrical phenotype associated with FGF3 mutations. [ABSTRACT FROM AUTHOR]
