<unk>  (AES or AEXS) is a rare genetic and endocrine syndrome which is characterized by an overexpression of<unk> , the enzyme responsible for the biosynthesis of the estrogen sex hormones from the androgens, in turn resulting in<unk> ive levels of circulating estrogens and, accordingly, symptoms of hyperestrogenism. It affects both sexes, manifesting itself in males as marked or complete phenotypical feminization (with the exception of the genitalia; i.e., no pseudohermaphroditism) and in females as hyperfeminization. To date, 30 males and 8 females with AEXS among 15 and 7 families, respectively, have been described in the medical literature.
