Additional support for a causal role of MIF in the etiology of T2D comes from a population-based study comparing the effect of four SNPs of MIF (rs755622, rs2070766, rs2070767, and rs1007888) on serum concentrations and the risk of T2D (MONICA/KORA Augsburg Study) [16]. The gene discussed is MIF; the disease is type 2 diabetes mellitus.
