Komplement-Komponente C5

Das C5-Gen kodiert die Komplement-Komponente C5, die eine wichtige Rolle bei der Aktivierung des Membran-Attack-Complexes (MAC) spielt. Da dieses protein der Angriffspunkt des Medikamentes Eculizumab spielt, sind bereits genetische Variationen entdeckt worden, die das Ansprechen auf den im Eculizumab vorhandenen monoklonalen Antikörper beeinflussen können. Des weiteren sind Assoziationen von Variationen mit Leberfibrose und rheumatischer Arthrtis beschrieben.
