Non-coding Variants in HK1 Account for 5% of Cases of Congenital Hyperinsulinism Without an Identified Genetic Cause

Rosenfeld Elizabeth , E. Boodhansingh Kara , A. Stanley Charles , Ganguly Arupa , D. De Leon Diva

Background: The genetic etiology of non-syndromic HI remains unknown in over 20% of all cases, and over 50% of diazoxide-responsive cases. Non-coding variants in HK1 have been suggested to cause HI by linkage-analysis (Pinney et al., 2008). More recently, variants within a regulatory region of HK1 intron 2 were reported in 17 individuals with HI (Wakeling et al., 2022). These variants have been proposed to cause HI by disrup...

Background: Congenital Hyperinsulinism International (CHI) is an international non-profit organization focused on improving the lives of patients and families living with hyperinsulinism (HI). Despite many advances in the care of patients with HI, long term neurologic outcomes have not significantly improved, highlighting the need for CHI’s goals for robust and rapidly translatable research. We describe the development of a collaborative research network...
