ZEN, Paulo R.G. et al. Report of a Brazilian patient with Wolfram syndrome. J. Pediatr. (Rio J.) [online]. 2002, vol.78, n.6, pp. 529-532. ISSN 0021-7557.  http://dx.doi.org/10.1590/S0021-75572002000600015.

ABSTRACT Objective: to report a case of a patient diagnosed with Wolfram Syndrome and brachydactyly type E. Wolfram Syndrome is characterized by the presence of diabetes mellitus, diabetes insipidus, atrophy of the optic nerve, alterations of the urinary tract, deafness and neurologic and psychiatric disorders. However, not all manifestations are present at diagnosis, indicating the necessity of long-term follow-up of these patients. This long-term follow-up should be extended to the patients' closest relatives, having in mind the increased risk of occurrence of psychiatric disorders and diabetes mellitus among the heterozygous carriers of Wolfram Syndrome. Description: male, white patients, only child of non-consanguineous parents, was healthy until four years of age, when he presented with polydipsia and polyuria, being diagnosed with diabetes mellitus type I. Since then, he has needed regular insulin use, but has followed an inadequate diet due to socioeconomic problems. He was evaluated by the genetic service when he was 11 years old. Brachydactyly was observed on physical examination. In the course of the complementary investigation, bilateral atrophy of the optic nerve was observed; the visual evoked potential and the electroretinogram were compatible with extensive optic nerve injury. Both retinas were normal. The presence of insulin-dependent diabetes mellitus together with atrophy of the optic nerve is a sufficient criterion for the diagnosis of Wolfram Syndrome. The molecular investigation confirmed the diagnosis of Wolfram Syndrome. Comments: the aim of the present report is to alert physicians about the association between diabetes mellitus and monogenic syndromes, such as Wolfram Syndrome.
