Impact of KIF6 Polymorphism rs20455 on Coronary Heart Disease Risk and Effectiveness of Statin Therapy in 100 Patients from Southern Iran.

BACKGROUND:The purpose of this study was to investigate the association between Trp719Arg (rs20455) and Coronary Heart Disease (CHD), and also Coronary Heart Disease reduction in individuals with this SNP during statin therapy in southern Iran. It has been shown that rs20455, which could affect the function of kinesin protein, is associated with Coronary Heart Disease and could be an effective factor for patients who take statin therapy. METHODS:Patients and control individuals were genotyped for rs20455 (SNP) using ARMS PCR (Amplification Refractory Mutation System and RFLP Length Polymorphism) analysis. The effect of kinesin family member 6 (KIF6) on statin therapy was also examined among patients who had a history of one or two heart attacks. RESULTS:It was found that rs20455 had a significant association with Coronary Heart Disease (Odds Ratio [OR] 3.17, 95% [CI] 1.68 to 5.98). In addition, statin therapy was more effective in rs20455 carriers than non-carriers, with 80% of the carriers showed positive response to this treatment. CONCLUSIONS:Trp 719Arg have an effect on development of Coronary Heart Disease but it is very useful for statin therapy. Overall, individuals with this duanyu1809 can take statin therapy to prevent the catastrophic consequences of Coronary Heart Disease.
