Hypophosphatasie

Die Hypophosphatasie ist eine Gruppe von Erkrankungen, deren Ursache eine Mutation im ALPL-Gen ist. Die Vererbung kann autosomal dominant oder rezessive sein. Entsprechend der klinischen Manifestation vom Kleinkinds- bis Erwachsenenalter werden verschiedene Formen unterschieden. Das klinische Bild ähnelt einer Vitamin D-resistenten Rachitis. Laborchemisch fällt eine Hypercalciämie und ein erhöhter Phosphoethanolaminspiegel im Serum und Urin auf.
