To analyze the frequencies of the carriers of such mutations in our cohort, we analyzed genes (HNF1A, HNF4A, HNF1B, INS, ABCC8, and KCNJ11) in which a significant number of missense mutations have previously been reported in MODY, neonatal diabetes mellitus, or early onset diabetes [57]. The gene discussed is ABCC8; the disease is MODY.
