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: curation

This variant is interpreted as a Uncertain Significance - Conflicting Evidence, for Deafness, in Autosomal Dominant manner. The following ACMG Tag(s) were applied: PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PP1 => Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease (PMID:25388789). BS1 => Allele frequency is greater than expected for disorder. -

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

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

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

The Arg653Cys variant in WFS1 has not been previously reported in individuals wi th hearing loss. This variant has been identified in 0.035% (3/8600) of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washi ngton.edu/EVS/; dbSNP rs201064551). Computational analyses (biochemical amino ac id properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide stro ng support for or against an impact to the protein. In summary, additional infor mation is needed to determine the clinical significance of this variant. -
