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

Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt WFS1 protein function. 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. ClinVar contains an entry for this variant (Variation ID: 166600). This variant has not been reported in the literature in individuals affected with WFS1-related conditions. This variant is present in population databases (rs376341411, gnomAD 0.04%). This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 662 of the WFS1 protein (p.Ser662Pro). -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The Ser662Pro variant in WFS1 has not been reported in individuals with hearing loss, but has been identified in 0.05% (2/4406) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/). Compu tational analyses (biochemical amino acid properties, conservation, AlignGVGD, P olyPhen2, and SIFT) suggest that the Ser662Pro variant may impact the protein, t hough this information is not predictive enough to determine pathogenicity. In s ummary, additional data is needed to determine the clinical significance of this variant. -
