Ectonucleotid-Pyrophosphatase/-Phosphodiesterase

Das ENPP1-Gen kodiert ein transmembranöses Glykoprotein, welches für die Spaltung von Phosphordiesterbindungen verantwortlich ist. Mutationen können zum autosomal rezessiven Phosphatdiabetes vom Typ 2 und zur ebenso rezessiven generalisierten arteriellen Verkalkung im Kindesalter vom Typ 1 führen. Des weiteren ist es ein Risikogen for Adipositas und Insulinresistenz.
