Leptin Receptor Gene Polymorphisms and the Risk of Non-Alcoholic Fatty Liver Disease and Coronary Atherosclerosis in the Chinese Han Population

Conclusions: LEPR Q223R polymorphisms may confer a significant risk of NAFLD and coronary atherosclerosis. The A allele in the K109R polymorphism might be considered an independent risk factor for coronary atherosclerosis in NAFLD patients.,Results: The LEPR Q223R A allele significantly reduced the risks of both NAFLD and coronary atherosclerosis (OR = 0.683, 95% CI: 0.527 - 0.884, P = 0.004 and OR = 0.724, 95% CI: 0.548 - 0.955, P = 0.022, respectively). Compared to controls, no significant differences in the genotype and allele frequencies of K109R were found in the NAFLD and coronary atherosclerosis populations, respectively. However, there was a significantly increased risk of coronary atherosclerosis in NAFLD patients who carried the K109R A allele (OR = 2.283, 95% CI: 1.556 - 3.348, P < 0.001).,Objectives: To investigate the association of LEPR polymorphisms at Q223R and K109R with the risks of NAFLD and coronary atherosclerosis in the Chinese Han population.,Patients and Methods: Genotypes of LEPR Q223R and K109R were determined by polymerase chain reaction followed by sequencing in patients with NAFLD (n = 554), coronary atherosclerosis (n = 421), and healthy controls (n = 550). Serum lipid profiles were determined using biochemical methods. Pearson’s χ2 test was used to check for Hardy-Weinberg equilibrium and to analyze the distributions of genotypes’ alleles between groups. Baseline characteristics were analyzed using student’s t-test, paired-samples t-te...
