Abstract :
Objective: It is suggested that C771G (His241Gln) polymorphism of MLXIPL gene might be a genetic risk factor for coronary artery disease (CAD); therefore, the aim of the present study was to investigate the association between C771G polymorphism of MLXIPL gene and the pathogenesis of CAD in Iranian patients with coronary artery stenosis and control subjects. Methods: Two hundred and five patients with coronary artery stenosis and 195 healthy control subjects were included in this study. MLXIPL genotypes were determined by polymerase chain reaction and restriction fragment length polymorphism (RFLP). Results: There was an association between the MLXIPL polymorphism and quantitative lipid traits in patient group. Distribution of the CC genotype of MLXIPL was more frequent in patients, (χ2=5.13; p 0.005) and after adjustment for classical CAD risk factors, the MLXIPL CC genotype was independently associated with CAD (OR=1.98, 95% CI, 1.12-4.11; p=0.02). Distribution of MLXIPL genotypes were significantly different as compared with the severity of stenosis (χ2=6.34; p 0.05). Conclusion: These results suggest that C771G polymorphism of MLXIPL gene is associated with stenosis and its severity.
