Genetic determinants of basal C-reactive protein expression in Filipino systemic lupus erythematosus families.

ABSTRACT: Basal C-reactive protein (CRP) is a heritable trait associated with long-term cardiovascular disease risk. Existing studies leave ambiguity over the key functional polymorphisms and fail to adjust for trans-acting effects. In a novel cohort of 285 Filipino systemic lupus erythematosus probands and their first-degree relatives, we quantified serum CRP and typed a dense map of CRP single-nucleotide polymorphisms (SNPs), along with SNPs in the interleukin-1 beta, interleukin-6 and apolipoprotein E genes. Ten CRP SNPs demonstrated association with basal CRP in a regression model (P=0.011-0.002). These delineated two haplotypes associated with high and low basal CRP expression (P=0.002). Differences in allele frequency were seen compared with Caucasian populations, enabling us to argue for an i
