Insulinrezeptor

Das Gen INSR kodiert den Insulinrezeptor, der für die metabilische Wirkung des Insulins in den Zellen verantwortlich ist. Verschiedene Krankheitsbilder stehen mit Mutationen diese Gens im Zusammenhang. Das sind die autosomal dominante Insulinresistenz und die beiden autosomal rezessiven Erkrankungen Donohue-Syndrom (Leprechaunismus) und Rabson-Mendenhall-Syndrom.
