Novel Gene Variant of Congenital Lipoid Adrenal Hyperplasia With Testicular Adrenal Rests.

A mutation in the steroidogenic acute regulatory protein () gene, which encodes a protein that plays a crucial role in steroid hormone synthesis, causes a severe form of congenital adrenal hyperplasia (CAH) known as lipoid CAH (LCAH). LCAH presents with primary adrenal insufficiency (PAI) as well as atypical genitalia. Individuals with LCAH require adrenal steroid hormone supplements for survival.
