Molecular characterization of WFS1 in patients with Wolfram syndrome.

ABSTRACT: Wolfram (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness) syndrome is a rare autosomal-recessive neurodegenerative disorder that is characterized by juvenile-onset diabetes mellitus, optic atrophy, diabetes insipidus, and sensorineural hearing impairment. A gene responsible for Wolfram syndrome (WFS1) has been identified on the short arm of chromosome 4 and subsequently mutations in WFS1 have been described. We have screened 12 patients with Wolfram syndrome from nine Dutch families for mutations in the WFS1-coding region by single-strand conformation polymorphism analysis and direct sequencing. Furthermore, we analyzed the mitochondrial genome for gross abnormalities and the A3243G point mutation in the leucyl-tRNA gene, because Wolfram syndrome shows phenotypic similar
