Summary
Genetic variations in C-reactive protein (CRP) may predict functional outcomes after ischemic stroke (IS). The CRP gene SNP rs1130864, specifically the T allele, was linked to poor functional outcomes in IS patients within three months.
Area of Science:
- Genetics and Neurology
- Biomarkers and Stroke Outcomes
Background:
- Ischemic stroke (IS) is a leading cause of long-term disability globally.
- C-reactive protein (CRP), an inflammatory marker, is an independent predictor of functional outcome post-IS.
- Single nucleotide polymorphisms (SNPs) in the CRP gene influence CRP levels and may impact stroke outcomes.
Purpose of the Study:
- To investigate the association between CRP gene genetic variations and functional disability after first-ever IS.
- To determine if specific CRP SNPs predict long-term functional outcomes in IS patients.
Main Methods:
- Genotyping of 1716 Western Chinese patients with first-ever IS for CRP SNPs rs1130864 and rs1800947.
- Assessment of functional outcome at 3 months post-IS using the modified Rankin Scale.
- Statistical analysis to test the association of CRP SNP genotypes with stroke outcome, adjusting for confounders.
Main Results:
- A significant association was found between the T allele of CRP SNP rs1130864 and poor functional outcome in IS patients.
- TT+CT genotypes of rs1130864 strongly predicted functional disability at 3 months post-IS, independent of other factors.
Conclusions:
- CRP gene SNP rs1130864 is an independent predictor of 3-month functional outcome in Han Chinese patients with first-onset IS.
- Further research in diverse ethnic populations is recommended to validate these findings.
