摘要: A two-stage genome-wide association study (GWAS) of the Cancer Genetic Markers Susceptibility (CGEMS) initiative identified single nucleotide polymorphisms (SNP) in 150 regions across genome that may be associated with prostate cancer (PCa) risk. We filtered these results to identify 43 independent SNPs where frequency risk allele was consistently higher cases than controls each five CGEMS populations. Genotype information for 22 obtained either directly by genotyping or indirectly imputation our PCa GWAS 500 and selected from a population-based case-control Sweden [Cancer Prostate (CAPS)]. Two were significantly (P<0.05). then genotyped two remaining (n=2,393) (n=1,222) CAPS found rs887391 at 19q13 highly (P=9.4 x 10(-4)). similar trend this SNP Johns Hopkins Hospital (JHH), albeit result not statistically significant. Altogether, among seven populations examined, an overall P=3.2 10(-7) combined allelic test. fine-mapping 110-kb region JHH revealed most strongly region. Additional confirmation studies are warranted.
