CRP gene haplotypes, serum CRP, and cerebral small-vessel disease: the Rotterdam Scan Study and the MEMO Study
Insights
C-reactive protein (CRP) gene variations are not associated with cerebral small-vessel disease (SVD). These findings suggest CRP is not a causal factor in SVD pathogenesis.
Area of Science:
- Genetics
- Neurology
- Cardiovascular Science
Background:
- Investigated the role of C-reactive protein (CRP) in atherosclerosis and atherothrombotic disease.
- Examined the association between CRP gene variations and cerebral small-vessel disease (SVD) in two independent cohorts: the Rotterdam Scan Study and the MEMO Study.
Discussion:
- Analyzed common CRP gene haplotypes using genotype-tagging single-nucleotide polymorphisms.
- Explored the relationship between CRP haplotypes and markers of cerebral SVD, including white matter lesions and lacunar infarcts, via regression analyses.
Key Insights:
- No significant association was found between CRP gene haplotypes and measures of cerebral SVD in either study cohort.
- CRP gene variations did not modify the association between serum CRP levels and cerebral SVD markers.
Outlook:
- The study suggests C-reactive protein (CRP) is unlikely to be causally implicated in the pathogenesis of cerebral small-vessel disease.
- Further research may explore other inflammatory markers or genetic factors in SVD development.
Background And Purpose:
It remains unclear whether C-reactive protein (CRP) is a serum marker for atherothrombotic disease or a causal factor in the pathogenesis of atherosclerosis. We explored the association between CRP gene variations and cerebral small-vessel disease (SVD) in the Rotterdam Scan Study (N=1035) and the MEMO Study (N=268).
Methods:
Common haplotypes within the CRP gene were determined by genotype-tagging single-nucleotide polymorphisms. Then their relation with periventricular and subcortical white matter lesions and the prevalence of lacunar brain infarcts was explored by regression analyses.
Results:
There was no association between CRP haplotypes and measures of cerebral SVD in either study. There was no effect modification of the association between serum CRP levels and measures of SVD by CRP haplotypes.
Conclusions:
Our observations suggest that CRP is not causally involved in the pathogenesis of SVD.
