Komplement-Komponente C9

Das C9-Gen kodiert die Complement Komponente 9. Diese ist am Membrane Attack Complex (MAC) beteiigt, welcher am Ende der Complementkaskade zur Auflösung der Zielbakterien führt. Mutationen können zu einem Mangel führen, wobei allerdings noch nicht klar ist, welchen Krankheitswert einem solchen Mangel zukommt.
