Genetic polymorphism in PDE4D gene and risk of ischemic stroke in Chinese population: a meta-analysis.

ABSTRACT:

Background

Stroke is the second most common cause of death and major cause of disability worldwide. The SNP 83 in PDE4D gene has been suggested as a risk factor in ischemic stroke, but direct evidence from genetic association studies remains inconclusive even in Chinese population.

Methods

Meta-analysis of case-control studies on the relationship between SNP 83 in PDE4D gene and susceptibility to ischemic stroke in Chinese population published domestically and abroad from January 2003 to September 2012.

Results

9 case-control studies were selected. Meta-analysis results showed that the significant association between SNP 83 and ischemic stroke was found under the dominant model (OR?=?1.34, 95% CI: 1.20-1.49) and recessive model (OR?=?1.45, 95% CI: 1.19-1.76) in Chinese population. In subgroup meta-analysis, SNP 83 and atherothrombotic stroke, rather than lacunar stroke, showed the significant association under the dominant model (OR?=?1.69, 95% CI: 1.41-2.01) and recessive model (OR?=?1.47, 95% CI: 1.04-2.06).

Conclusions

The results suggest that SNP 83 in PDE4D gene is significantly associated with susceptibility to ischemic stroke in Chinese population.
