DMRT1: An Ancient Sexual Regulator Required for Human Gonadogenesis.

ABSTRACT: Transcriptional regulators related to the invertebrate sexual regulators doublesex and mab-3 occur throughout metazoans and control sex in most animal groups. Seven of these DMRT genes are found in mammals, and mouse genetics has shown that one, Dmrt1, plays a crucial role in testis differentiation, both in germ cells and somatic cells. Deletions and, more recently, point mutations affecting human DMRT1 have demonstrated that its heterozygosity is associated with 46,XY complete gonadal dysgenesis. Most of our detailed knowledge of DMRT1 function in the testis, the focus of this review, derives from mouse studies, which have revealed that DMRT1 is essential for male somatic and germ cell differentiation and maintenance of male somatic cell fate after differentiation. Moreover, ectopic DMRT1
