These channels are composed of four subunits of SUR1 and four subunits of KIR6.2 encoded by the ABCC8 and KNCJ11 genes, respectively. Inactivating mutations in these two g...

In Brief: The authors performed whole genome sequencing on 135 patients with congenital hyperinsulinaemia (CHI) who had negative genetic testing for previously known CHI genes. They identified nine different non-coding de novo variants (carried by 14 probands) located in a regulatory region of HK1 intron 2 that co-segregated with disease in families.Comment: HK1 is a disallowed gene in the liver and pancreatic beta cells. Th...
