A total of 7 variants including 2 variants of ABCC8 were identified.[21] Recently, a study in UK found that the mitochondrial m.3243A > G and mutations in HNF1B were responsible for the majority of mutations in syndromic diabetes genes, and 11 patients, about 4% in 1280 patients, were found the variant for ABCC8.[22] However, a study carried on South India showed HNF1A and ABCC8 to be the most frequently mutated MODY genes, with 7.2% (11/152) and 3.3% (5/152) respectively.[23]. Here, ABCC8 is linked to MODY.
