Hämojuvelin
Das HJV-Gen kodiert ein wichtiges Regulatorprotein, Hämojuvelin, des Eisenstoffwechsels. Dieses Protein ist in der Signalkaskade vor dem Hepcidin anzutreffen. Es reguliert die Hepcidin expression und Mutationen entwickeln deshalb einen ähnlichen Phänotyp einer juvenilen Hämochromatose (Typ 2A), die in diesem Falle autosomal rezessiv vererbt wird.
