“…The structure of IDOL gene can be divided into an N-terminal FERM domain and a C-terminal RING domain. The two domains are separated by a short connecting band 22,23 . In fact, IDOL showed ubiquitination activity on LDLR.…”
Hyperlipidemia is one of the main risk factors that contributed to atherosclerosis and coronary artery disease (cAD). in the present study, our objective was to explore whether some genetic variants of human iDoL gene were associated with hyperlipidemia among Han population in Xinjiang, china. We designed a case-control study. A total of 1,172 subjects (588 diagnosed hyperlipidemia cases and 584 healthy controls) of Chinese Han were recruited. We genotyped three SNPs (rs9370867, rs909562, and rs2072783) of IDOL gene in all subjects by using the improved multiplex ligation detection reaction (iMLDR) method. our study demonstrated that the distribution of the genotypes, the dominant model (AA vs GG + GA), and the overdominant model (AA + GG vs GA) of the rs9370867 SNP had significant differences between the case group and controls (all P < 0.001). For rs909562 and rs2072783, the distribution of the genotypes, the recessive model (AA + GA vs GG) showed significant differences between the case subjects and controls (P = 0.002, P = 0.007 and P = 0.045, P = 0.02, respectively). After multivariate adjustment for several confounders, the rs9370867 SNP is still an independent risk factor for hyperlipidemia [odds ratio (OR) = 1.380, 95% confidence interval (CI) = 1.201-1.586, P < 0.001]. The rs9370867 of human IDOL gene was associated with hyperlipidemia in Han population.

Hyperlipidemia is one of the main risk factors that contributed to atherosclerosis and coronary artery disease (CAD) 2,3. Previous studies on molecular mechanisms of hyperlipidemia revealed that multiple risk factors,
