WS1 gene mutation analysis of Wolfram syndrome in a Chinese patient and a systematic review of literatures.
Wolfram syndrome is a rare hereditary disease characterized by diabetes mellitus and optic atrophy. The outcome of this disease is always poor. WFS1 gene mutation is the main cause of this disease. A patient with diabetes mellitus, diabetes insipidus, renal tract disorder, psychiatric abnormality, and cataract was diagnosed with Wolfram syndrome. Mutations in open reading frame (ORF) of WFS1 gene was analyzed by sequencing. Mutations in WFS1 gene was also summarized by a systematic review in Pubmed and Chinese biological and medical database. Sequencing of WFS1 gene in this patient showed a new mutation, 1962G>A, and two other non-sense mutations, 2433A>G and 2565G>A. Systematic review included 219 patients in total and identified 172 WFS1 gene mutations, most of which were located in Exon 8. These mutations in WFS1 gene might be useful in prenatal diagnosis of Wolfram syndrome.
