Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by impaired cortisol synthesis.^[1][2] It results from the deficiency of one of the five enzymes required for the synthesis of cortisol in the adrenal cortex.^[3] Most of these disorders involve excessive or deficient production of hormones such as glucocorticoids, mineralocorticoids, or sex steroids,^[4][2] and can alter development of primary or secondary sex characteristics in some affected infants, children, or adults.^[5] It is one of the most common autosomal recessive disorders in humans.^[6][7][8]
