Objective: To examine the main effect of 10 single nucleotide polymorphisms (SNPs) in contribution to abdominal obesity and study whether there is an interaction in the 10 SNPs in the cause of abdominal obesity.
Methods: A total of 820 subjects were randomly selected and no individual was related. Individual polymorphism and interactions were available for analyses.
Results: C allele carrier (CC + TC) was significantly higher than that of TT genotype (OR (95%CI) = 0.68 (0.52 - 0.90), P = 0.005). A 5-dimension gene-to-gene interaction model existed among rs135539, rs2016520, rs10865710, rs1805192 and rs709158 on the incidences of abdominal obesity.
Conclusions: The C allele in rs2016520 is significantly associated with a lower rate of abdominal obesity. And there is an interaction among rs2016520, rs135539, rs10865710, rs1805192 and rs709158 on the incidences of abdominal obesity.
