== Disease ==
[https://www.uniprot.org/uniprot/CP19A_HUMAN CP19A_HUMAN] Defects in CYP19A1 are a cause of aromatase excess syndrome (AEXS) [MIM:[https://omim.org/entry/139300 139300]; also known as familial gynecomastia. AEXS is characterized by an estrogen excess due to an increased aromatase activity.  Defects in CYP19A1 are the cause of aromatase deficiency (AROD) [MIM:[https://omim.org/entry/613546 613546]. AROD is a rare disease in which fetal androgens are not converted into estrogens due to placental aromatase deficiency. Thus, pregnant women exhibit a hirsutism, which spontaneously resolves after post-partum. At birth, female babies present with pseudohermaphroditism due to virilization of extern genital organs. In adult females, manifestations include delay of puberty, breast hypoplasia and primary amenorrhoea with multicystic ovaries.<ref>PMID:8265607</ref> <ref>PMID:8530621</ref> <ref>PMID:9211678</ref> 
== Function ==
[https://www.uniprot.org/uniprot/CP19A_HUMAN CP19A_HUMAN] Catalyzes the formation of aromatic C18 estrogens from C19 androgens.
