Single-nucleotide polymorphisms and haplotypes in the CRP gene. (A) Schematic representation of the CRP gene drawn to scale. Exons are represented as blue boxes. Dots represent the locations of the seven single-nucleotide polymorphisms investigated in this study. Zigzag lines indicate truncation of nucleotides. (B) Haplotypes and names are in agreement with those used in previous publications ,. The nucleotides are stated according to the plus strand. The frequencies of haplotypes are given as percentages.
