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.Ala575Gly variant (rs71524360) has not been reported in the medical literature in association with hearing loss nor has it been previously identified in our laboratory. It is listed in the Genome Aggregation Database (gnomAD) browser with a frequency in Latino populations of 0.10% (identified in 35 out of 34,416 chromosomes, including 1 homozygote). The alanine at codon 575 is moderately conserved considering 13 species (Alamut software v2.9), and computational analyses return mixed results regarding the effect of this variant on WFS1 protein structure/function (SIFT: tolerated, PolyPhen2: benign, and Mutation Taster: disease causing). Thus, based on the available information, the clinical significance of the p.Ala575Gly variant cannot be determined with certainty. -
