  Congenital adrenal hyperplasia due to 17α-hydroxylase deficiency is an uncommon form of congenital adrenal hyperplasia resulting from a defect in the gene for the enzyme CYP17A1.
  17-alpha hydroxylase deficiency causes 1% of congenital adrenal hyperplasia.
  All patients have female external genitalia due to increased deoxycorticosterone and arterial hypertension.
  It produces decreased synthesis of both cortisol and sex steroids, with resulting increase in mineralocorticoid production. (...)
