What is (are) Wolfram syndrome ?
Wolfram syndrome, which is also known by the acronym DIDMOAD, is an inherited condition characterized by diabetes insipidus (DI), childhood-onset diabetes mellitus (DM), a gradual loss of vision caused by optic atrophy (OA), and deafness (D). There are two types of Wolfram syndrome (type 1 and type 2) which are primarily differentiated by their genetic cause. Type 1 is caused by changes (mutations) in the WFS1 gene, while type 2 is caused by mutations in the CISD2 gene. Both forms are inherited in an autosomal recessive manner. Treatment is symptomatic and supportive.
