    Wolfram syndrome is an autosomal recessive disorder with probable locus heterogeneity. Only insulin-dependent diabetes mellitus and progressive optic-nerve atrophy are necessary to make the diagnosis, but associated findings include diabetes insipidus, sensorineural hearing loss, ataxia, peripheral neuropathy, urinary-tract atony, and psychiatric illnesses. We performed clinical and molecular studies on four consanguineous families with 16 affected individuals. We point out a new phenotypic variant with absent diabetes insipidus, presence of peptic ulcer disease and bleeding tendency secondary to a platelet aggregation defect. The same phenotypic variant turned out to be a genotypic variant with linkage to a second Wolfram syndrome locus (WFS2) on chromosome 4q22-24.
