Involvement in diseasei

Cortisone reductase deficiency (CRD)2 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionIn CRD, activation of cortisone to cortisol does not occur, resulting in adrenocorticotropin-mediated androgen excess and a phenotype resembling polycystic ovary syndrome (PCOS).
