- Abstract
Dyschromatosis symmetrica hereditaria (DSH, MIM 127400) is an autosomal dominant pigmentary genodermatosis. Pathogenic mutations in the double-RNA-specific adenosine deaminase ( DSRAD) gene encoding an RNA editing enzyme have recently been identified. To identify gene mutations of DSRAD in Chinese patients with DSH. Three unrelated Chinese patients with DSH were subjected to mutation detection in DSRAD. Two had family histories of DSH. All the coding exons and their flanking sequences were amplified and sequenced. All three patients had heterozygous mutations including one non-sense, one frameshift and one missense mutation in DSRAD. Two novel mutations, c.3169delC (p.L1057fs) and c.3247C→T (p.R1083C), and one recurrent mutation c.1420C→T (p.R474X), were found in this series of Chinese patients with DSH.
