Genes affected

HSD17B3 (HGNC:5212): (hydroxysteroid 17-beta dehydrogenase 3) This isoform of 17 beta-hydroxysteroid dehydrogenase is expressed predominantly in the testis and catalyzes the conversion of androstenedione to testosterone. It preferentially uses NADP as cofactor. Deficiency can result in male pseudohermaphroditism with gynecomastia. [provided by RefSeq, Jul 2008]

HSD17B3 Gene-Disease associations (from GenCC):

• 46,XY disorder of sex development due to 17-beta-hydroxysteroid dehydrogenase 3 deficiency
