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]

ClinVar contains an entry for this variant (Variation ID: 4511). This variant is also known as 2114G‚ÜíA W648X. This premature translational stop signal has been observed in individual(s) with autosomal recessive Wolfram syndrome (PMID: 8808601, 9771706, 10521293, 28432734). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs104893879, gnomAD 0.002%). This sequence change creates a premature translational stop signal (p.Trp648*) in the WFS1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 243 amino acid(s) of the WFS1 protein. For these reasons, this variant has been classified as Pathogenic. -
