AES results when the function of aromatase is impaired. The aromatase protein (pictured) is required for the biosynthesis of oestrogens like oestradiol in the human body.
Aromatase deficiency is a rare condition characterized by extremely low levels or complete absence of the enzyme aromatase activity in the body.[2] It is an autosomal recessive disease resulting from various mutations of gene CYP19 (P450arom) which can lead to ambiguous genitalia and delayed puberty in females, continued linear growth into adulthood and osteoporosis in males and virilization in pregnant mothers. As of 2020[update], fewer than 15 cases have been identified in genetically male individuals[3] and at least 30 cases in genetically female individuals.[4]
