OGG1 mRNA expression by the genotypes of SNPs, using data from the HapMapa.

aGenotyping data and mRNA expression levels for OGG1 Ser326Cys by genotypes obtained from the HapMap phase II release 23 data from EBV-transformed lymphoblastoid cell lines from 270 individuals. CHB: 45 unrelated Han Chinese in Beijing; JPT: 45 unrelated Japanese in Tokyo; CEU: 90 Utah residents with ancestry from northern and western Europe; YRI: 90 Yoruba in Ibadan, Nigeria.bTwo-side Student's t test within the stratum.cP values for the trend test of OGG1 mRNA expression among 3 genotypes for each SNP from a general linear model.dThere were missing data because genotyping data were not available.
