Abstract: The SRY gene (sex-determining region on the Y chromosome; MIM *480000) is responsible for initiating male gonadal development. However, only 15-20% of the cases of XY gonadal dysgenesis are due to mutations in its sequence. Recently, heterozygous mutations in the NR5A1 gene (nuclear receptor subfamily 5, group A, member 1; MIM +184757) have been described in association with ovarian failure and disorders of testis development with or without adrenal failure. Here we describe a case of XY complete gonadal dysgenesis due to a p.D293N homozygous mutation in the NR5A1 gene, with normal SRY and no adrenal failure.
Key words: gene mutations, NR5A1 gene, XY gonadal dysgenesis
