MODY tip diyabet, pankreas β hücrelerinin işlev bozukluğu ve ardından insülin üretimi ile sonuçlanan, monojenik, otozomal dominant bir diyabet formudur.
MODY tanısına sahip olan hastaları belirlemek için mevcut strateji, diyabetin genç yaşta başlaması, otozomal dominant kalıtım ve insülin gereksiniminin olmamaması gibi klinik özellikleri saptamaktır.
HNF1A-MODY, kronik mikrovasküler diyabet komplikasyonları açısından yüksek riskli, hipergliseminin ilerleyici karakterde olduğu, çocukluk, ergenlik veya erken yetişkinlik döneminde başlayan, ketotik olmayan diyabet tipidir (1).
Bu yazıda rastlantısal tanıalan HNF1-A geninde yeni bir (c, 787C> T (p.R263C) (c.Arg263ys)) gen mutasyonuna bağlı HNF1A-MODY 3 tanısı alan bir hasta sunuldu.
