[PMID 19088850] rs10830962, rs4753426, and rs10830963 were significantly associated with higher fasting plasma glucose concentrations and reduced OGTT- and IVGTT-induced insulin release. rs3781638 displayed significant association with lower fasting plasma glucose levels and increased OGTT-induced insulin release
[PMID 19324940] A study totaling 19,000+ Europeans concluded that rs10830963 had the most influence of any MTNR1B gene SNP on the risk for type-2 diabetes. Specifically, the (G) allele increased the risk of isolated impaired fasting glycemia (OR=1.64, P=5.5x10(-11)) but not isolated impaired glucose tolerance.
