To evaluate the usefulness of the two public databases, HapMap and Perlegen, in facilitating studies associating polymorphisms in these genes with drug response, we examined 111 single-nucleotide-polymorphisms from 13 ABCtransporter genes in Singaporean-Chinese, European-Americans and African-Americans. We found that genotype data from the HapMap/Perlegen databases are generally transferable to different sampling of the same population and to similar populations residing elsewhere. However, not all ABC-transporter family genes are amenable to SNP-tagging due to the low tagging-efficiency of low-LD genes resulting in negligible cost-savings. Hence, alternative approaches may have to be explored for low-LD ABC genes.
