Large-Scale Single-Nucleotide Polymorphism (SNP) and Haplotype Analyses, Using Dense SNP Maps, of 199 Drug-Related Genes in 752 Subjects: the Analysis of the Association between Uncommon SNPs within Haplotype Blocks and the Haplotypes Constructed with Haplotype-Tagging SNPs

To optimize the strategies for population-based pharmacogenetic studies, we extensively analyzed single-nucleotide polymorphisms (SNPs) and haplotypes in 199 drug-related genes, through use of 4,190 SNPs in 752 control subjects. Drug-related genes, like other genes, have a haplotype-block structure, and a few haplotype-tagging SNPs (htSNPs) could represent most of the major haplotypes constructed with common SNPs in a block. Because our data included 860 uncommon (frequency 0.03.
