Genetic control of gonadal differentiation.
The study of naturally occurring mutations in humans and induced mutations in mice that cause sex reversal has been instrumental in the cloning and functional analysis of genes involved in gonadal differentiation. Several genes required for this complex developmental process have now been identified. The genes LIM1, WT1 and FTZ-F1 have been demonstrated to be involved in the formation of the gonads prior to their differentiation as testes or ovaries. Subsequent sex-specific gonadal differentiation appears to be mediated by the SRY and SOX9 genes in the testis, and the DAX-1 gene in the ovary.
