An attenuated form of congenital virilizing adrenal hyperplasia.
Overview
abstract
The families of two patients with hirsutism and oligomenorrhea were studied with iv ACTH (Cortrosyn) stimulation. The parents responded with a combined incremental rise of progesterone and 17-hydroxyprogesterone greater than 6.5 ng/dl.min, a response seen in the heterozygote parents of patients with congenital virilizing adrenal hyperplasia (CVAH). One sibling in one family responded as do heterozygous subjects, while two other siblings responded normally. The abnormal response of the two pairs of parents and the sibling along with the pattern of steroid secretion observed in the propositi suggest that the so-called adult-onset CVAH is a mild form of the homozygous state of CVAH.
