Non-glucocorticoid-remediable aldosteronism in an infant with low-renin hypertension.

A 6-week-old male with severe hypertension is presented. He was found to have hyperaldosteronism and a negative long polymerase chain reaction (PCR) test for glucocorticoid-remediable aldosteronism. His mother and maternal grandfather also had severe hypertension. A case is made for the possible diagnosis of familial hyperaldosteronism type II at a very early age.
