Genome-wide association (GWA) studies have identified multiple loci at which common variants modestly influence the risk of developing colorectal cancer (CRC). To enhance power to identify additional loci with similar effect sizes, we conducted a meta-analysis of two GWA studies, comprising 13,315 individuals genotyped for 38,710 common tagging SNPs. We(More)
While gliomas are the most common primary brain tumors, their etiology is largely unknown. To identify novel risk loci for glioma, we conducted genome-wide association (GWA) analysis of two case-control series from France and Germany (2269 cases and 2500 controls). Pooling these data with previously reported UK and US GWA studies provided data on 4147(More)
To identify new risk variants for chronic lymphocytic leukemia (CLL), we conducted a genome-wide association study of 299,983 tagging SNPs, with validation in four additional series totaling 2,503 cases and 5,789 controls. We identified four new risk loci for CLL at 2q37.3 (rs757978, FARP2; odds ratio (OR) = 1.39; P = 2.11 x 10(-9)), 8q24.21 (rs2456449; OR(More)
A genome-wide association study of chronic lymphocytic leukaemia (CLL) suggested that common variants at 15q25.2 (rs783540) and 18q21.1 (rs1036935) influence CLL. To validate these associations and explore their relationship with CLL risk we genotyped case-control datasets from Poland, UK and Italy totalling 1428 cases and 1920 controls. Combined data from(More)
BACKGROUND Genomewide association studies have identified 10 low-penetrance loci that confer modestly increased risk for colorectal cancer (CRC). Although they underlie a significant proportion of CRC in the general population, their impact on the familial risk for CRC has yet to be formally enumerated. The aim of this study was to examine the combined(More)
The plasminogen pathway plays an important role in the behavior of many tumors including lung cancer. Hence genetic variants encoding plasminogen activator (PLAU), plasminogen receptor (PLAUR), plasminogen activator inhibitor 1 (PAI-1) and plasminogen activator inhibitor 2 (PAI-2) may contribute to lung cancer prognosis. To investigate this proposition we(More)
The common single-nucleotide polymorphism (SNP) rs3802842 at 11q23.1 has recently been reported to be associated with risk of colorectal cancer (CRC). To examine this association in detail we genotyped rs3802842 in eight independent case-control series comprising a total of 10 638 cases and 10 457 healthy individuals. A significant association between the C(More)
We performed a meta-analysis of 3 genome-wide association studies to identify additional common variants influencing chronic lymphocytic leukemia (CLL) risk. The discovery phase was composed of genome-wide association study data from 1121 cases and 3745 controls. Replication analysis was performed in 861 cases and 2033 controls. We identified a novel CLL(More)
Recent genome-wide association studies (GWAS) have identified common genetic risk variants for chronic lymphocytic leukemia (CLL). Testing SNPs individually for an association in GWAS necessitates the imposition of a very stringent P value to address multiple testing. While this reduces false positives, it may result in true associations being missed. Thus,(More)
BACKGROUND There is variability in the outcome of patients with chronic lymphocytic leukemia with apparently the same stage of disease. Identifying genetic variants that influence patients' outcome and response to treatment may provide important insights into the biology of the disease. DESIGN AND METHODS We investigated the possibility that genetic(More)
