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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Ala878Thr variant in WFS1 has not been previously reported in individuals with hearing loss or Wolfram syndrome, but has been identified in 6/16452 of Sou th Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broa dinstitute.org; dbSNP rs570527044). Computational prediction tools and conservat ion analysis suggest that the p.Ala878Thr variant may not impact the protein, th ough this information is not predictive enough to rule out pathogenicity. In sum mary, the clinical significance of the p.Ala878Thr variant is uncertain. -

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 878 of the WFS1 protein (p.Ala878Thr). This variant is present in population databases (rs570527044, gnomAD 0.03%). 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: 229645). 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) has been performed at Invitae 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. 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. -

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 rs570527044 in Wolfram's syndrome yet. -
