Paroxysmal nocturnal hemoglobinuria (PNH) definition and facts. PNH is a rare, chronic disease that causes rapid breakdown of red blood cells and can result in reddish or cola-colored urine, often seen in the early morning after urination. PNH is due to a spontaneous mutation in gene material. PNH is not inherited.
