Background And Purpose: Elevated levels of C-reactive protein (CRP) are found in up to three quarters of patients with acute ischemic stroke and are associated with poor outcome. We investigated whether haplotypes representing common variations in the CRP gene are associated with levels of CRP in patients with acute ischemic stroke.
Methods: We included 185 patients with ischemic stroke in whom CRP was measured within 24 h of symptom onset. Common haplotypes within the CRP gene were determined by 3 genotype-tagging single-nucleotide polymorphisms (SNPs).
Results: Four haplotypes with frequencies >5% covered 99.2% of the genetic variation. Haplotype 4 (CCG, frequency 8.3%) was associated with a 20.6 mg/l (95% CI, 9.8-30.4) stronger increase in CRP level as compared with haplotype 1 (CTC, frequency 33.7%).
Conclusion: Variation in the CRP gene is associated with levels of CRP in acute ischemic stroke.
