Polymorphism in the C-reactive protein (CRP) gene affects CRP levels in plasma and one early marker of atherosclerosis in men: The Health 2000 Survey

AbstractBackground. C-reactive protein (CRP) is an inflammatory protein that may play a role in the pathogenesis of cardiovascular disease (CVD). However, its status as a causal risk factor is still controversial. CRP gene single nucleotide polymorphisms (SNPs) have been shown to associate with CRP concentration, but not convincingly with early atherosclerotic changes. Objective. We assessed whether CRP genotypes or their haplotypes associate with plasma CRP levels or carotid artery intima-media thickness (IMT) or carotid artery elasticity (CAE) in a Finnish middle-aged study population. Methods. We genotyped CRP gene polymorphisms −717A>G (rs2794521), −286C>T>A (rs3091244), +1059G>C (rs1800947), +1444C>T (rs1130864) and +1846G>A (rs1205) and measured CRP concentration in a sub-population (N=1332, mean age 58.2 ± 8.0, women n=727 and men n=605) of a large Finnish cross-sectional health examination survey, The Health 2000 Study, carried out in 2000–2001. Results. Significant association (both sexes p<0.000...
