Publicly Available Single Nucleotide Polymorphisms in Genes Possibly Susceptible to Antiepileptic Drug Resistance in Healthy Koreans

ABSTRACT

BACKGROUND: The completion of the human genome project means that a high-quality reference sequence of the gene-rich portion of the human genome is now available. However, the strong influence of ethnic, geographical, and other characteristics of study populations on the frequencies of different single-nucleotide polymorphisms (SNPs) makes it questionable whether foreign SNP data should be used in domestic studies. METHODS: Twenty-seven possible candidate genes of antiepileptic drug (AED) resistance were resequenced in a DNA pool from 200 healthy Koreans to identify SNPs and calculate their minor allele frequencies (MAFs). RESULTS: A total of 98 SNPs were present in 22 of the 27 genes 28 were in the coding regions, 34 were in introns, 23 were in 5' near genes, 10 were in 5' untranslated regions, and 3 were in 3' near genes. CONCLUSIONS: The comparative analysis using the pooled DNA adopted in the present study was highly reliable in estimating MAFs and was compatible with the common disease/common variant hypothesis. The reported data on 98 publicly available SNPs of genes possibly associated with AED resistance that be useful to researchers with limited availability of domestic SNP data.
