Interleukin 27 polymorphisms, their association with insulin resistance and their contribution to subclinical atherosclerosis. The GEA Mexican study.

Abstract

Our previous data suggest that the heterodimeric interleukin-27 (IL-27) could participate in the developing of insulin resistance (IR). Our aim was to assess the participation of IL-27p28 gene single nucleotide polymorphisms (SNPs) as markers for IR, subclinical atherosclerosis (SA) and cardiovascular risk factors in a Mexican population. Five IL-27p28 SNPs (rs153109, rs40837, rs17855750, rs26528 and rs181206) were genotyped in 856 individuals with IR and 644 participants without IR. Under inheritance models adjusted for confounding factors, the rs153109A (0.78[0.64-0.94] Padditive = 0.008, 0.58[0.41-0.82] Precessive = 0.002, 0.57[0.38-0.83] Pcodominant2 = 0.004), rs26528T (0.78[0.64-0.94] Padditive = 0.008, 0.61[0.43-0.88] Precessive = 0.007, 0.57[0.38-0.84] Pcodominant2 = 0.004) and rs40837A (0.76[0.63-0.92] Padditive = 0.004; 0.60[0.42-0.86] Precessive = 0.005; 0.54[0.37-0.80] Pcodominant2 = 0.002) alleles were related with a decreased risk of IR. Moreover, AAATA haplotype that contains the protector alleles was related with 17% lower risk of presenting IR (0.83 [0.71-0.98], P = 0.023). After adjusting for potential confounding variables, IL-27p28 SNPs were not associated with SA. However, some SNPs were associated with hypertension (rs26528 and rs40837) and increased total abdominal fat (rs17855750) in non-IR individuals, whereas in IR subjects we observed an association of rs26528 and rs40837 with hypoadiponectinemia. Our evidence suggests that rs40837A, rs153109A, and rs26528T alleles could be envisaged as protective markers for IR. Some polymorphisms showed an association with hypertension, low adiponectin levels, and increased total abdominal fat.
