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]

Potent mutations in WFS1 gene are associated with Wolfram's syndrome, an autosomal recessive condition, which cause diabetes mellitus, diabetes insipidus, deafness and optic atrophy. However no sufficient evidence is found to ascertain the role of this particular variant rs150894674 in Wolfram's syndrome yet. -
