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 Asp267Asn variant in WFS1 has not been reported in individuals with hearing loss, but has been identified in 0.07% (6/8600) of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs145677667). Although this variant has been seen in the general population, it s frequency is not high enough to rule out a pathogenic role. Computational ana lyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, an d SIFT) do not provide strong support for or against an impact to the protein. I n summary, additional data is needed to determine the clinical significance of t his variant. -
