          Abstract

          A síndrome de Wolfram consiste na associação de diabetes mellitus e atrofia óptica. Outros achados comuns são surdez neurossensorial, alterações do trato urinário e distúrbios neurológicos. Tem padrão de herança autossômico recessivo com penetrância incompleta e expressividade variável. O objetivo deste relato é apresentar paciente que apresenta todas as características da síndrome de Wolfram (ou síndrome DIDMOAD). JFP, negro, 23 anos, apresenta diabetes mellitus e insipidus, atrofia óptica, surdez neurossensorial, polineuropatia periférica, neuropatia autonômica, bexiga neurogênica, dilatação do trato urinário, infecções repetidas do trato urinário e azoospermia. Os exames clínico-oftalmológico, retinografia, angiografia fluoresceínica, eletrorretinografia (ERG) e potencial visual evocado (PVE) mostram padrão de normalidade retiniana e de atrofia de nervos ópticos. A síndrome de Wolfram deve ser lembrada em casos de atrofia óptica associados a diabetes, poliúria, polidipsia ou a qualquer uma das alterações apresentadas.

          Translated abstract

          Wolfram syndrome consists of the association of diabetes mellitus with optic atrophy. Other common findings are deafness, urinary tract and neurological disorders. It is an autossomic recessive disease, with incomplete penetrance and variable expressivity. The aim of this case report is to describe a patient who presents all the characteristics of Wolfram syndrome (DIDMOAD syndrome). JFP, African - American, 23 years old, presents with diabetes mellitus and insipidus, optic atrophy, deafness, peripheral polyneuropathy, autonomic neuropathy, neurogenic bladder, urinary tract dilation with recurrent infections, and azoospermia. Clinical examination, retinography, fluorescein angiogram, eletroretinography (ERG) and visual evocated potencial (VEP) revealed no retinal disorders and bilateral optic atrophy. Wolfram syndrome must be remembered in cases of optic atrophy in association with diabetes, urinary disorders, or any of the described alterations.

            Non-syndromic progressive hearing loss DFNA38 is caused by heterozygous missense mutation in the Wolfram syndrome gene WFS1.

            Dominantly inherited progressive hearing loss DFNA38 is caused by heterozygosity for a novel mutation in WFS1, the gene for recessively inherited Wolfram syndrome. Wolfram syndrome is defined by juvenile diabetes mellitus and optic atrophy and may include progressive hearing loss and other neurological symptoms. Heterozygotes for other Wolfram syndrome mutations generally have normal hearing. Dominant deafness defined by DFNA38 is more severe than deafness of Wolfram syndrome patients and lacks any syndromic features. In a six-generation kindred from Newfoundland, Canada, WFS1 Ala716Thr (2146 G-->A) was shared by all deaf members of the family and was specific to deaf individuals. The causal relationship between this missense mutation and deafness was supported by two observations based on haplotype and mutation analysis of the kindred. First, a relative homozygous for the mutation was diagnosed at age 3 years with insulin-dependent diabetes mellitus, the central feature of Wolfram syndrome. Second, two relatives with normal hearing had an identical haplotype to that defining DFNA38, with the exception of the base pair at position 2146. Other rare variants of WFS1 co-inherited with deafness in the family could be excluded as disease-causing mutations on the basis of this hearing-associated haplotype. The possibility that 'mild' mutations in WFS1 might be a cause of non-syndromic deafness in the general population should be explored.
