Abstract

Dyschromatosis symmetrica hereditaria (DSH) is a hereditary skin disease characterized by the presence of hyperpigmented and hypopigmented macules on face and dorsal aspects of the extremities that appear in infancy or early childhood. Genetic studies have identified mutations in the double-stranded RNA-specific adenosine deaminase (DSRAD) gene, encoding double-stranded RNA-specific adenosine deaminase, to be responsible for this disorder. Here, we report two novel mutations c.2116 G > A (E706K) and c.2848 C > T (Q950X) in the DSRAD gene identified in two Chinese pedigrees with DSH. This study should be useful for genetic counseling and prenatal diagnosis for affected families and in expanding the database on DSRAD gene mutations in DSH.
