Komplement C2-Mangel

Der Mangel an Komplementfaktor C2 ist eine autosomal rezessive Erkrankung, die durch reduzierte C2-Plasmaspiegel und eine erhöhte Infektanfälligkeit gekennzeichnet ist. Da ein C2-Defizit von sonst gesunden Menschen sehr gut kompensiert wird, ist bei einer erhöhten Infektanfälligkeit stets auch nach anderen Ursachen zu suchen.
