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...
