Principal causes include congenital adrenal hyperplasia (CAH), X-linked congenital adrenal hypoplasia (AHC), familial glucocorticoid deficiency (FGD) caused by adrenal cortical unresponsiveness to ACTH, adrenoleukodystrophy (ALD) and triple A syndrome (Allgrove syndrome) (1, 2). This evidence concerns the gene POMC and X-linked adrenoleukodystrophy.
