To identify the DSRAD gene; mutations in three Chinese families with dyschromatosis symmetrica hereditaria. All exons of DSRAD gene were analyzed in each person of these families with PCR-DNA sequencing. DNA samples from 100 unrelated, normally pigmented adult individuals were also included as control. We identified a missense mutation of C3220T (R1074C) in DSRAD gene in family A, and another missense mutation of G3325T (D1109Y) in DSRAD gene in family B and C. No same mutation was found in unaffected individuals in the families and the controls. We found two special missense mutations in DSRAD gene in three families of dyschromatosis symmetrica hereditaria. These mutations may impair DSRAD protein function, and as a consequence, cause skin dyschromatosis.
