We have studied these selected microRNAs in altogether 20 individuals examined for hypercortisolism (Cushing's syndrome) by low-dose dexamethasone test [12] and for adrenal insufficiency or late onset congenital adrenal hyperplasia (21-hydroxylase deficiency) by ACTH (tetracosactide) test [13]. The gene discussed is POMC; the disease is adrenal gland hyperfunction.
