Gonadal dysgenesis (GD) is a disorder of sex development. Formerly, 46,XY GD was also known as 46,XY sex reversal (SRXY). In 46,XY GD, the gonadal histology can range from fibrous streak gonads to partial GD with presence of testicular tissue. The phenotype of patients with 46,XY GD can vary from normal female to genital ambiguity to an undervirilized male. Mutations involving the testis-determining gene SRY, and other genes involved in sex determination, such as the genes WT1, DHH, NR5A1, SOX9, FOG2/ZFPM2 and MAP3K1 have been identified.
