Summaries for Aromatase Excess Syndrome

About this section
Genetics Home Reference : 25 Aromatase excess syndrome is a condition characterized by elevated levels of the female sex hormone estrogen in both males and females. Males with aromatase excess syndrome experience breast enlargement (gynecomastia) in late childhood or adolescence. The bones of affected males grow and develop more quickly and stop growing sooner than usual (advanced bone age). As a result males have an early growth spurt, typically during late childhood, with short stature as an adult. Affected females rarely show signs and symptoms of the condition, but they may have increased breast growth (macromastia), irregular menstrual periods, and short stature. The ability to have children (fertility) is usually normal in both males and females with aromatase excess syndrome.

MalaCards based summary : Aromatase Excess Syndrome, also known as aexs, is related to gynecomastia and estrogen excess. An important gene associated with Aromatase Excess Syndrome is CYP19A1 (Cytochrome P450 Family 19 Subfamily A Member 1), and among its related pathways/superpathways are Steroid hormone biosynthesis and Peptide hormone metabolism. The drugs Letrozole and Aromatase Inhibitors have been mentioned in the context of this disorder. Affiliated tissues include bone, breast and liver, and related phenotypes are gynecomastia and short stature

OMIM : 57 Aromatase excess syndrome is an autosomal dominant disorder characterized by increased extraglandular aromatization of steroids that presents with heterosexual precocity in males and isosexual precocity in females (Tiulpakov et al., 2005). (139300)

UniProtKB/Swiss-Prot : 75 Aromatase excess syndrome: An autosomal dominant disorder characterized by increased extraglandular aromatization of steroids that presents with heterosexual precocity in males and isosexual precocity in females.

Disease Ontology : 12 A reproductive system disease characterized by autosomal dominant inheritance of increased extraglandular aromatization of steroids resulting in heterosexual precocity in males and isosexual precocity in females that has material basis in fusion of the CYP19A1 gene with various partners, brought about by translocations and resulting in gain of function of the CYP19A1 gene.
