Background and aims: In recent years, the results of the association between Tribbles Pseudokinase 1 (TRIB1) gene polymorphism and the risk of coronary artery disease (CAD) and stroke are inconsistent. This study aimed to systematically review the literature on TRIB1 gene polymorphisms and susceptibility to coronary atherosclerotic heart disease (CAD) and stroke.
Methods: This study collected studies published until May 2022 through a systematic search of PubMed, Web of Science, and Google Scholar databases. After a systematic literature search, pooled odds ratio (OR) and their corresponding 95 % confidence interval (CI) were used to assess the strength of the association.
Results: We identified 6 studies on rs17321515, including 12,892 controls and 4583 patients, and 3 on rs2954029, including 1732 controls and 1305 patients. In different genetic models, the rs2954029 genetic polymorphism significantly increased the risk of CAD and stroke. In the codominant model, the AA genotype increased the risk of CAD and stroke (OR = 1.74, 95 % CI = 1.39-2.17, P < 0.001); the TA genotype also increased the prevalence of CAD and stroke risk (OR = 1.39, 95 % CI = 1.18-1.64, P < 0.001). Compared with the control group, the TT + TA genotype increased the risk of CAD and stroke in the dominant genetic model (OR = 1.46, 95 %CI = 1.25-1.71, P < 0.001), and in the recessive model, the TA + AA genotype increased the risk of CAD and stroke (OR = 1.41, 95 % CI = 1.15-1.72, P < 0.001). In addition, the TRIB1 rs17321515 polymorphism was not found to be associated with the risk of CAD and stroke, which may be related to other factors such as race.
Conclusions: The rs2954029 A allele was significantly associated with an increased risk of CAD and stroke, according to the present meta-analysis. However, the association of rs17321515 polymorphism with susceptibility to CAD and stroke has not been found in this study.
