Stroke is the second-leading cause of global mortality and the third leading cause of disability.Numerous in-dependent studies have reported that genetic mutations such as single nucleotide polymorphisms (SNPs) within genes may alter an individual's susceptibility towards several health disorders that subsequently lead to the development of stroke incidence. To date, constructive information that summarizes this particular relationship is limited. Hence, this comprehensive review focuses on the role of SNPs in facilitating susceptibility to several health disorders including brain aneurysms, atrial fibrillation, atherosclerosis, and hyperlipidemia, and their association with the development of higher stroke incidence. We discussed a total of 33 SNPs in this review that includes 11 SNPs associated with brain aneurysms, 4 SNPs associated with atrial fibrillation, 13 SNPs associated with atherosclerosis, and 5 SNPs associated with hyperlipidemia. The SNPs data could assist in determining an individual's risk of different health disorders and subsequently stroke. Therefore, pharmacogenomics could be applied to effectively provide appropriate personalized medications and genetic counseling.

The rs9958947 single nucleotide polymorphism (SNP) resides in the promoter region of the lipase G (LIPG) gene. This newly discovered SNP increases the risk of stroke in some Asian populations, including Chinese and Korean populations. Stroke is one of the top 5 leading causes of death in Malaysia, so it is of interest to investigate whether this SNP is associated with stroke risk in the Malaysian population. Therefore, this study investigates this association through a case-control study on a Malaysian population along with a comprehensive metaanalysis. Genotyping of LIPG rs9958947 SNP was performed for 241 Malaysians using real-time polymerase chain reaction, and the odds ratios (OR) with 95% confidence intervals were calculated. The meta-analysis was conducted using the software Comprehensive Meta-Analysis ver. 2.2.064. A p value less than 0.05 was considered statistically significant. We observed that the mean age of Malaysian stroke patients was less than that of stroke patients from Korea and China. The meta-analysis showed that the LIPG rs9958947 SNP was significantly associated with an increased risk of ischemic stroke in Asian populations (dominant (CC vs. CT+TT): OR=1.45, p0.05) and blood lipid levels.
