Genes affected

WFS1 (HGNC:12762): (wolframin ER transmembrane glycoprotein) This gene encodes a transmembrane protein, which is located primarily in the endoplasmic reticulum and ubiquitously expressed with highest levels in brain, pancreas, heart, and insulinoma beta-cell lines. Mutations in this gene are associated with Wolfram syndrome, also called DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy, and Deafness), an autosomal recessive disorder. The disease affects the brain and central nervous system. Mutations in this gene can also cause autosomal dominant deafness 6 (DFNA6), also known as DFNA14 or DFNA38. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2009]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 504 of the WFS1 protein (p.Pro504Leu). This variant is present in population databases (rs28937892, gnomAD 0.009%). This missense change has been observed in individuals with autosomal recessive Wolfram syndrome (PMID: 9771706, 15277431, 24890733). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 4512). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on WFS1 protein function. Experimental studies have shown that this missense change affects WFS1 function (PMID: 16806192). For these reasons, this variant has been classified as Pathogenic. -

Reported as heterozygous in two patients with type 1 diabetes (PMID: 31264968); Published functional studies demonstrate that P504L leads to increased degradation of the WFS1 protein (PMID: 16806192); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 15277431, 24890733, 31589614, 15151504, 11161832, 12955714, 9771706, 36208030, 36147510, 34746052, 37444722, 34258273, 31264968, 15605410, 28432734, 16806192) -

Variant summary: WFS1 c.1511C>T (p.Pro504Leu) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 3.6e-05 in 249854 control chromosomes (gnomAD and publication data). c.1511C>T has been reported in the literature in multiple individuals affected with Wolfram Syndrome 1 (Inoue_1998, Gmez-Zaera_2001, Astuti_2017). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function and this variant results in decreasing protein stability (Hofmann_2006) . The following publications have been ascertained in the context of this evaluation (PMID: 28432734, 11161832, 16806192, 9771706). Four submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic (n=3) and likely pathogenic (n=1). Based on the evidence outlined above, the variant was classified as pathogenic. -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The WFS1 c.1511C>T variant is predicted to result in the amino acid substitution p.Pro504Leu. This variant has been reported in the compound heterozygous state in multiple patients with Wolfram syndrome (Inoue et al. 1998. PubMed ID: 9771706; Chaussenot et al. 2014. PubMed ID: 24890733) and was also reported in two patients with type 1 diabetes (Table S6, Yu et al. 2019. PubMed ID: 31264968). This variant is reported in 0.0085% of alleles in individuals of Latino descent in gnomAD. This variant is interpreted as pathogenic. -
