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]

Collection Method: clinical testing

The p.Glu273Lys variant in WFS1 has not been previously reported in individuals with hearing loss, but has been reported in ClinVar (Variation ID 215382) as of uncertain significance. It has also been identified in 0.16% (54/34416) of Latin o chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadins titute.org; dbSNP rs142428158). Although this variant has been seen in the gener al population, its frequency is not high enough to rule out a pathogenic role. C omputational prediction tools and conservation analysis do not provide strong su pport for or against an impact to the protein. In summary, the clinical signific ance of the p.Glu273Lys variant is uncertain. -
