Genes affected

NR5A1 (HGNC:7983): (nuclear receptor subfamily 5 group A member 1) The protein encoded by this gene is a transcriptional activator involved in sex determination. The encoded protein binds DNA as a monomer. Defects in this gene are a cause of XY sex reversal with or without adrenal failure as well as adrenocortical insufficiency without ovarian defect.
