Abstract

Loss-of-function ABCC8 variants are the commonest cause of congenital hyperinsulinism. On a systematic search of our databases, the p.(Gly111Arg) ABCC8 variant was identified in 26 individuals, of which 23 were from the Indian Agarwal community. Haplotype analysis subsequently confirmed that p.(Gly111Arg) is a founder variant in the Agarwal population.
