Similar findings were observed in terms of VDR genotype, haplotype, and LD among our T2DM patients: the frequency of VDR FoxI, ApaI, and Taq1 genotypes observed in T2DM patients was similar to that reported previously among T1DM and healthy volunteers; the haplotypes VDR FoxI T/ApaI C/Taq1 T/BsmI C and FoxI T/ApaI A/Taq1 C/BsmI T were the major VDR haplotypes in T2DM patients, as well as T1DM patients and healthy controls; and the VDR ApaI, TaqI, and BsmI variants were in strong LD, while FoxI was in weak LD, with other VDR variants in T1DM and T2DM patients. The gene discussed is VDR; the disease is type 1 diabetes mellitus.
