A fundamental challenge to contemporary genetics is to distinguish rare missense alleles that disrupt protein functions from the majority of alleles neutral on protein activities. High-throughput experimental tools to securely discriminate between disruptive and non-disruptive missense alleles are currently missing. Here we establish a scalable cell-based strategy to profile the biological effe...

Spinocerebellar ataxia type 13 (SCA13) is an autosomal dominantly inherited neurodegenerative disorder of the cerebellum caused by mutations in the voltage gated potassium channel KCNC3. To identify novel pathogenic SCA13 mutations in KCNC3 and to gain insights into the disease prevalence in the Netherlands, we sequenced the entire coding region of KCNC3 in 848 Dutch cerebellar ataxia patients ...

PURPOSE Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a developmental disease characterized by a complex eyelid malformation associated or not with premature ovarian failure (POF). BPES is essentially an autosomal dominant disease, due to mutations in the forkhead box L2 (FOXL2) gene, encoding a forkhead transcription factor. More than one hundred unique FOXL2 mutations have be...

Inactivating germline mutations in DNA mismatch repair (MMR) genes are diagnostic for Lynch syndrome. However, the clinical significance of missense variants is uncertain. A threshold level of compromised MLH1 expression, correlating with greater protein instability and MMR functional defect, has been identified to help classify the pathogenicity of missense variants.

A novel missense mutation in the gene for gap-junction protein α3 (GJA3) associated with autosomal dominant " nuclear punctate " cataracts linked to chromosome 13qA novel missense mutation in the gene for gap-junction protein α3 (GJA3) associated with autosomal dominant " nuclear punctate " cataracts linked to chromosome 13q.

The impact of somatic missense mutation on cancer etiology and progression is often difficult to interpret. One common approach for assessing the contribution of missense mutations in carcinogenesis is to identify genes mutated with statistically nonrandom frequencies. Even given the large number of sequenced cancer samples currently available, this approach remains underpowered to detect drive...

Random mutagenesis of human papillomavirus type 16 (HPV16) E1 was used to generate E1 missense mutants defective for interaction with either hUBC9 or 16E1-BP, two cDNAs encoding proteins that have been identified by their ability to interact with HPV16 E1 in two-hybrid assays. hUBC9, the human counterpart of Saccharomyces cerevisiae UBC9, is a ubiquitin-conjugating enzyme known to be involved i...

Next-generation sequencing is transforming our understanding of human genetic variation but assessing the functional impact of novel variants presents challenges. We analyzed missense variants in the integrin αIIbβ3 receptor subunit genes ITGA2B and ITGB3 identified by whole-exome or -genome sequencing in the ThromboGenomics project, comprising ∼32,000 alleles from 16,108 individuals. We analyz...

Hereditary Hemorrhagic Telangiectasia syndrome (HHT) or Rendu-Osler-Weber (ROW) syndrome is an autosomal dominant vascular disorder. Two most common forms of HHT, HHT1 and HHT2, have been linked to mutations in the endoglin (ENG) and activin receptor-like kinase 1 (ACVRL1or ALK1) genes respectively. This work was designed to examine the pathogenicity of 23 nucleotide variations in ACVRL1 gene d...

Background To investigate the role of the anti-Müllerian hormone (AMH) signalling pathway in the pathophysiology of idiopathic primary ovarian insufficiency (POI) and age at natural menopause (ANM) using a genetic approach MaterialsAndMethods DNA sequencing was used to detect the genotype distribution and allele frequency of the genes AMH and AMH receptor II (AMHR2) in 120 cases of idiopathic P...
