Association of rs4618210A>G variant in gene with myocardial infarction: A case-control study in Iran.

Myocardial infarction (MI) is the leading cause of death all over the world. The pivotal roles of Phospholipase C like 2 gene () in calcium homeostasis and immune responses make this gene as a potential candidate for its role in MI pathogenesis. The present study was undertaken to investigate whether rs4618210A>G polymorphism in gene contribute to MI etiology. A hospital-based case-control study with 600 subjects, including 300 MI patients and 300controls, was conducted. Genotyping of rs4618210 polymorphism was performed using amplification refractory mutation system-polymerase chain reaction (ARMS PCR) method. Data were analyzed using logistic regression analysis. No significant association was found between the rs4618210 alleles and MI risk.However, a significantly increased risk of MI was observed among carriers of the AG genotype (OR= 1.91; 95% CI = 1.24 - 2.93; = 0.003) compared with AA homozygote. In a dominant mode of inheritance for G allele (GG + AG vs. AA), the frequency of the carriers of at least one G allele was higher in cases compared to controls (OR= 1.56; 95% CI: 1.03 - 2.36; = 0.037). Our study provided further evidence that gene polymorphism may serve as a prognostic marker for MI.
