Objectives: KLF11 is a member of the Sp1/KLF family transcription factor which contains three C2H2 zinc finger domains. To date, two KLF11 mutations (p.T220M and p.A347S) have been identified in three families clinically diagnosed with type 2 diabetes. The aim of our study is to report clinical and molecular characteristics of a KLF11 mutation-carrying family clinically diagnosed with type 1 diabetes (T1D).Methods:...

Background: Vertical transfer of maternal cells to the fetus via the placenta leads to maternal microchimerism (MMc) in children. Previous studies from USA have shown that the prevalence and degree of MMc was significantly higher in patients with type 1 diabetes (T1D) than in their unaffected siblings and control individuals. To date, however, the frequency of MMc in non-Caucasian T1D patients remains to be examined.Methods</stro...
