Association between miR-30 polymorphism and ischemic stroke in Chinese population

Area of Science:

• Genetics
• Neurology
• Molecular Biology

Background:

• Ischemic stroke (IS) is a prevalent cerebrovascular disease with incompletely understood causes.
• The miR-30 gene is a potential factor in IS, but its association with single-nucleotide polymorphisms (SNPs) and IS risk remains unexplored.

Purpose of the Study:

• To investigate the relationship between specific miR-30 gene polymorphisms (rs2222722, rs1192037, rs10095483, and rs16827546) and the risk of developing IS.

Main Methods:

• Genotyping of four miR-30 polymorphisms (rs2222722, rs1192037, rs10095483, rs16827546) using the SNPscan technique.
• Analysis involved 248 IS patients and 230 matched controls.

Main Results:

• A significant association was found between the rs2222722 polymorphism and an increased risk of IS.
• Specific genotype (AA vs. GG) and allele (G vs. A) analyses showed significant associations (P < 0.05).
• miR-30a expression levels were significantly higher in IS patients compared to controls (P < 0.05).

Conclusions:

• The rs2222722 polymorphism in the miR-30 gene is significantly associated with an elevated risk of ischemic stroke.
• These findings highlight the potential role of miR-30 gene variations in the pathogenesis of IS within the Chinese population.
