Description

Mutations in KCNJ11 gene can cause decreased production and secretion of insulin. This can lead to MODY which may be responsive to oral sulfonylureas. Though the prevalence of this particular variant rs80356625 is seen in neonatal diabetes and hyperinsulinism, no sufficient evidence found for its significance in MODY yet.
