Polyzystische Nierenerkrankung mit hyperinsulinämischer Hypoglycämie

Die hyperinsulinämische Herperglycämie mit polyzystischer Nierenerkrankung ist eine autosomal rezessive Erkrankung, die durch eine homozygote PMM2-Promotor-Mutation oder eine compound heterozygote Promotormutation mit einer kodierenden PMM2-Mutation ausgelöste wird. Die Erkrankung manifestiert sich früh in der Kindheit.

Epidemiologie

17 derartige Fälle in 11 Familien sind bisher beschrieben.[1]
