Male specific expression suggests role of DMRT1 in human sex determination.
Sex determination in mammals is controlled by various transcription factors. Following the identification of SRY on the Y chromosome, several other factors have been identified. They can normally be identified as being involved in sex determination by the identification of sex reversal mutations or deletions, functional studies, and also by male-specific expression patterns in embryos. Here, it is shown that DMRT1, recently demonstrated to be deleted in 9p monosomies associated with sex reversal, is specifically expressed during sex determination in the genital ridge of human male, but not female, embryos, similar to SRY.
