We performed a three-phase genome-wide association study (GWAS) using cases and controls from a genetically isolated population, Ashkenazi Jews (AJ), to identify loci associated with breast cancer risk. In the first phase, we compared allele frequencies of 150,080 SNPs in 249 high-risk, BRCA1/2 mutation-negative AJ familial cases and 299 cancer-free AJ(More)
Genome-wide association studies of breast cancer have identified multiple single nucleotide polymorphisms (SNPs) that are associated with increased breast cancer risks in the general population. In a previous study, we demonstrated that the minor alleles at three of these SNPs, in FGFR2, TNRC9 and MAP3K1, also confer increased risks of breast cancer for(More)
Women with hereditary nonpolyposis colorectal cancer (HNPCC) have a high risk for endometrial cancer (EC) and frequently present with a gynecologic cancer as their first or sentinel malignancy. Identification of these patients is important given their personal and family risk for synchronous and metachronous tumors. The revised Bethesda Guidelines provide(More)
Recently, we identified a novel breast cancer susceptibility locus at 6q22.33 following a genome-wide association study in the Ashkenazi Jewish genetic isolate. To replicate these findings, we did a case-control association analysis on 6q22.33 (rs2180341) in an additional 487 Ashkenazi Jewish breast cancer cases and in an independent non-Jewish,(More)
BACKGROUND In this study we aimed to evaluate the role of a SNP in intron 1 of the ERCC4 gene (rs744154), previously reported to be associated with a reduced risk of breast cancer in the general population, as a breast cancer risk modifier in BRCA1 and BRCA2 mutation carriers. METHODS We have genotyped rs744154 in 9408 BRCA1 and 5632 BRCA2 mutation(More)
