  • Title: Associations of intercellular adhesion molecule-1 rs5498 polymorphism with ischemic stroke: A meta-analysis.
    Author: Gao H, Zhang X.
    Journal: Mol Genet Genomic Med; 2019 Jun; 7(6):e643. PubMed ID: 30997752.
    Abstract:
    BACKGROUND: Recently, associations between intercellular adhesion molecule-1 (ICAM-1) rs5498 polymorphism and ischemic stroke (IS) were investigated by several pilot studies, but with inconsistent results. In this study, a meta-analysis was performed to better assess the relationship between ICAM-1rs5498 polymorphism and IS. METHODS: PubMed, Medline, Embase, and CNKI were searched for eligible studies. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) to evaluate associations between ICAM-1 rs5498 polymorphism and IS. RESULTS: Totally 16 studies with 2,596 cases and 11,800 controls were analyzed. A significant association with IS was observed for rs5498 polymorphism in GG versus AA + AG (recessive model, p = 0.009, OR = 1.62, 95% CI 1.13-2.32, I2  = 76%) in overall population. Further subgroup analyses showed that rs5498 polymorphism was significantly associated with IS in Caucasians in AA versus AG + GG (dominant model, p = 0.03, OR = 0.52, 95% CI 0.29-0.95, I2  = 72%), GG versus AA + AG (recessive model, p < 0.0001, OR = 2.98, 95% CI 2.05-4.31, I2  = 19%), and A versus G (allele model, p = 0.005, OR = 0.50, 95% CI 0.31-0.81, I2  = 81%). However, no any positive findings were detected for Asians. CONCLUSIONS: Our findings indicated that rs5498 polymorphism was significantly associated with individual susceptibility to IS in Caucasians, but not in Asians.
