Phosphomannomutase 2

Das Gen PMM2 kodiert eine Phosphomutatse, die an der Glcosilierung der Mannose beteiligt ist. Mutationen führen zu autosomal rezessiven Erkrankungen. Liegen diese ausschließlich im kodierenden Bereich führen sie zur kongenitale Glykosilierungsstörung 1A, wenn jedoch eine Promotor-Mutation beteiligt ist, so kommt es zur polyzystische Nierenerkrankung mit hyperinsulinämischer Hypoglycämie.
