rs1799884, known also as the -30 SNP of the GCK gene, has been associated with type-2 diabetes.

This SNP is one of 4 relatively common SNPs reported to represent risk for type-2 diabetes in the DESIR prospective study of 3,877 Caucasian participants. Under a recessive model, the odds ratio for rs1799884(A;A) homozygotes is 2.70 (CI: 1.51-4.83, p=0.0008); under an additive model, the odds ratio is 1.34 (CI: 1.07-1.69, p=0.01). For the 4 SNPs, each risk allele increased type-2 diabetes risk by 1.34x (p=2x10e-6), with an odds ratio of 2.48 (CI: 1.59-3.86) for carriers of 4 or more compared to those with one or none (risk alleles).[PMID 17977958]
