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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJul 20, 2015Variant classified as Uncertain Significance - Favor Benign. The p.Ser790Leu var iant in WFS1 has been previously reported as a polymorphism in a study of Japane se individuals with Wolfram syndrome (Matsunaga 2014). This variant has also bee n identified in 9/8474 East Asian chromosomes by the Exome Aggregation Consortiu m (ExAC, http://exac.broadinstitute.org; dbSNP rs369107336). Although this varia nt has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation anal yses suggest that the Ser790Leu variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, whi le the clinical significance of the p.Ser790Leu variant is uncertain, these data suggest that it is more likely to be benign. -
