The potential association between the K121Q (A/C, rs1044498) polymorphism in the ectonucleotide pyrophosphatase/phosphodiesterase (ENPP1) gene and risk of diabetic kidney disease (DKD) has been investigated.
We confirmed the association between the rs1044498 SNP in ENPP1 and diabetic nephropathy, especially among obese diabetic patients, in the Taiwanese population.
