Wolframin is a protein that in humans is encoded by the WFS1 gene.[4][5][6]


Wolframin is a transmembrane protein.[6] Wolframin appears to function as a cation-selective ion channel.[7]

Clinical significance[edit]

Mutations in this gene are associated with an autosomal recessive syndrome characterized by insulin-dependent diabetes mellitus and bilateral progressive optic atrophy, usually presenting in childhood or early adult life. Diverse neurologic symptoms, including a predisposition to psychiatric illness, may also be associated with this disorder. A large number and variety of mutations in this gene, particularly in exon 8, can be associated with this syndrome. Mutations in this gene can also cause autosomal dominant deafness 6 (DFNA6), also known as DFNA14 or DFNA38.[6]

Mutations in this gene have also been associated with congenital cataracts.[8]
