Genetic epidemiology and genetic associations


BackgroundHuman chromosomal region 8q24 contains several genes which could be functionally related to cancer, including the proto-oncogene c-MYC. However, the abundance of associations around 128 Mb on chromosome 8 could mask the appearance of a weaker, but important, association elsewhere on 8q24.

MethodsIn this study, we completed a meta-analysis of results from nine genome-wide association studies for seven types of solid-tumor cancers breast, prostate, pancreatic, lung, ovarian, colon, and glioma to identify additional associations that were not apparent in any individual study.

ResultsFifteen SNPs in the 8q24 region had meta-analysis p-values < 1E-04. In particular, the region consisting of 120,576,000-120,627,000 bp contained 7 SNPs with p-values < 1.0E-4, including rs6993464 p = 1.25E-07. This association lies in the region between two genes, NOV and ENPP2, which have been shown to play a role in tumor development and motility. An additional region consisting of 5 markers from 128,478,000 bp - 128,524,000 around gene POU5F1B had p-values < 1E-04, including rs6983267, which had the smallest p-value p = 6.34E-08. This result replicates previous reports of association between rs6983267 and prostate and colon cancer.

ConclusionsFurther research in this area is warranted as these results demonstrate that the chromosomal region 8q24 may contain a locus that influences general cancer susceptibility between 120,576 and 120,630 kb.
