Background: Wolfram syndrome is an autosomal recessive disorder caused by mutations in the WFS1 gene. Clinical heterogeneity has been reported both within and between families with WFS1 mutations.

Subjects: The first case was diagnosed with insulin-dependent diabetes mellitus with positive for pancreatic autoantibodies and had a ketoacidotic attack in the follow-up period. The second case presented initially with optic atrophy and was diagnosed with behavioral and psychiatric problems at an early age. The third case had early onset insulin-dependent diabetes with multiple anomalies and congenital hypothyroidism. Many of these features have not been reported previously in patients with Wolfram syndrome. In all three patients homozygous mutations in WFS1 were identified.

Conclusion: Wolfram syndrome is a disease where the characteristic features may present at different times. A diagnosis of Wolfram syndrome should therefore be considered even in the absence of the full spectrum of clinical features.
