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:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces phenylalanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 413 of the WFS1 protein (p.Phe413Val). This variant is present in population databases (rs71524356, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with WFS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 166584). 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) indicates that this missense variant is not expected to disrupt WFS1 protein function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

PreventionGenetics, part of Exact Sciences

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The WFS1 c.1237T>G variant is predicted to result in the amino acid substitution p.Phe413Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0093% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

p.Phe413Val in Exon 8 of WFS1: This variant is not expected to have clinical sig nificance due to a lack of conservation across species, including mammals. Many mammals, including other primates, have a valine (Val) at this position despite high nearby amino acid conservation. In addition, computational analyses (PolyPh en2, SIFT, AlignGVGD) do not suggest a high likelihood of impact to the protein. This variant has been identified in 4/66740 of European chromosomes by the Exom e Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs71524356 ). -

Ambry Genetics

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Collection Method:research

Potent mutations in WFS1 gene are associated with Wolfram's syndrome, an autosomal recessive condition, which cause diabetes mellitus, diabetes insipidus, deafness and optic atrophy.However no sufficient evidence is found to ascertain the role of this particular variant rs71524356 in Wolfram's syndrome yet. -
