Wolfram syndrome 1 Pathogenic:5
PVS1, PM2, PM3 -
- -
Mutations in WFS1 gene are associated with Wolfram's syndrome, an autosomal recessive condition, which cause diabetes mellitus, diabetes insipidus, deafness and optic atrophy. rs1362648752 variant is also seen in patients with Diabetes Mellitus. However, the role of this particular variant is yet to be ascertained. -
The variant c.409_424dup (p.Val142Glyfs*110) in the WFS1 gene is reported as pathogenic for Wolfram syndrome 1 and WFS1-related spectrum disorders in ClinVar (Variation ID: 4519), and as pathogenic in the Global Variome shared LOVD database v.3.0. It creates a shift in the reading frame, which is predicted to result in a premature stop codon 110 amino acids downstream and in a truncated protein or protein loss due to nonsense-mediated messenger decay (NMD). The variant is reported with an estimated allele frequency of 0.0000439 in gnomAD exomes, with no homozygous individuals reported. According to the systematic review conducted by De Heredia et al. (2013) about disease-causing mutations in 412 patients with Wolfram syndrome, the c.409_424dup (p.Val142Glyfs*110) is present in about 6.53% of cases (PMID:23429432). -
Variant summary: WFS1 c.409_424dup16 (p.Val142GlyfsX110) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 4.4e-05 in 205180 control chromosomes. c.409_424dup16 has been reported in the literature in multiple individuals affected with Wolfram Syndrome 1 (e.g. Gomez-Zaera_2001). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 11161832).ClinVar contains an entry for this variant (Variation ID: 4519). Based on the evidence outlined above, the variant was classified as pathogenic. -
not provided Pathogenic:2
This sequence change creates a premature translational stop signal (p.Val142Glyfs*110) in the WFS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in WFS1 are known to be pathogenic (PMID: 12955714). This variant is present in population databases (rs767046229, gnomAD 0.01%). This premature translational stop signal has been observed in individuals with autosomal recessive Wolfram syndrome (PMID: 1161832, 26875006, 32141364). This variant is also known as 425ins16. ClinVar contains an entry for this variant (Variation ID: 4519). For these reasons, this variant has been classified as Pathogenic. -
Frameshift variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Identified in 6.53% of individuals with Wolfram syndrome (de Heredia et al., 2013); This variant is associated with the following publications: (PMID: 17568405, 20738327, 34758253, 15605410, 26875006, 32179840, 32141364, 21602428, 12955714, 27395765, 11161832, 15151504, 21446023, 22238590, 15277431, 33841295, 23429432) -

WFS1-Related Spectrum Disorders Pathogenic:1
Across a selection of available literature, the WFS1 c.409_424dupGGCCGTCGCGAGGCTG (p.Val142GlyfsTer110) variant has been identified in in seven individuals with Wolfram syndrome, including in a homozygous state in four individuals from three families and in a compound heterozygous state in three unrelated individuals (Domenech et al. 2004; Chaussenot et al. 2011; Rohayem et al. 2011). A systematic review of disease-causing variants associated with Wolfram syndrome indicated that the p.Val142GlyfsTer110 variant is present in 6.53% of patients and is a common cause of Wolfram syndrome in the Spanish population (de Heredia et al. 2013; Domenech et al. 2004). The variant was absent from 98 control chromosomes and is reported at a frequency of 0.000103 in the Latino population of the Genome Aggregation Database. Based on the collective evidence, the p.Val142GlyfsTer110 variant is classified as pathogenic for WFS1-related spectrum disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
