Use:CAH Panel 1 (21-Hydroxylase vs 11Beta-Hydroxylase Deficiency) - Deficiency of 21-Hydroxylase is the most frequent cause of congenital adrenal hyperplasia (accounting for ~95% of cases) and 11Beta-Hydroxylase is the second most frequent (~5% of cases). Deficiencies of these two enzymes result in the accumulation of distinct steroid precursors.
