title: No evidence of mutations in four candidate genes for male sex determination/differentiation in sex-reversed XY females with campomelic dysplasia.
abstract: Campomelic dysplasia (Cd) occurs combined with sex reversal resulting in XY females. The recent identification of candidate genes for sex determination/differentiation and of a sex determining region on the human Y chromosome prompted the authors to study these genes for mutations in patients with Cd and sex reversal. In a total of five cases, no evidence for a mutation in the genes SRY, ZFY, ZFX, MEA and some anonymous Y-linked sequences was found. In addition to Southern analysis, gene expression of ZFY, ZFX and MEA was found to be normal as well. It is concluded that sex reversal in this condition is due to mutation in a so far unidentified gene which may act secondary to the testis-determining factor (TDF).
