INTRODUCTION Previous studies have demonstrated that common breast cancer susceptibility alleles are differentially associated with breast cancer risk for BRCA1 and/or BRCA2 mutation carriers. It is currently unknown how these alleles are associated with different breast cancer subtypes in BRCA1 and BRCA2 mutation carriers defined by estrogen (ER) or(More)
BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1(More)
Several common alleles have been shown to be associated with breast and/or ovarian cancer risk for BRCA1 and BRCA2 mutation carriers. Recent genome-wide association studies of breast cancer have identified eight additional breast cancer susceptibility loci: rs1011970 (9p21, CDKN2A/B), rs10995190 (ZNF365), rs704010 (ZMIZ1), rs2380205 (10p15), rs614367(More)
Genome-wide association studies (GWAS) have identified 12 epithelial ovarian cancer (EOC) susceptibility alleles. The pattern of association at these loci is consistent in BRCA1 and BRCA2 mutation carriers who are at high risk of EOC. After imputation to 1000 Genomes Project data, we assessed associations of 11 million genetic variants with EOC risk from(More)
BACKGROUND Male breast cancer (MBC) is a rare disease and little is known about its etiopathogenesis. Array comparative genomic hybridization (aCGH) provides a method to quantitatively measure the changes of DNA copy number and to map them directly onto the complete linear genome sequences. The aim of this study was to investigate DNA imbalances by aCGH and(More)
Gastric carcinomas (GCs) with high-level microsatellite instability (MSI-H) are characterized by widespread mutations at coding and non-coding mononucleotide repeats. Deletions at coding mononucleotide tracts are predicted to cause frameshift mutations and alter normal protein functions. Mutations affecting non-coding mononucleotide repeats may lead to(More)
read with great interest the paper by Akbari and colleagues [1] in a recent issue of Breast Cancer Research. Th e authors reported on the absence of RAD51C mutations in 454 patients with BRCA1/2-negative familial breast cancer/ovarian cancer (BC/OC). In the initial report by Meindl and colleagues [2], RAD51C mutations were identifi ed in 6 out of 480(More)
Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of synthetic lethality that exists between one of the components of the BER pathway, PARP1 (poly ADP ribose(More)
BACKGROUND Male breast cancer (MBC) is a rare disease and little is known about its aetiology. Germ-line mutations of BRCA2 and, at lower frequency, of BRCA1 are implicated in a relatively small proportion of MBC cases. Common polymorphic variants in BRCA1 and BRCA2 genes may represent breast cancer (BC) susceptibility alleles and could be associated with a(More)
Using PTT combined with SSCP, we screened the entire BRCA1 and BRCA2 coding sequences in 136 unrelated patients, recruited from oncology units in Rome and Naples and including 107 females with breast cancer, 10 with ovarian cancer and 19 males affected with breast cancer. Female patients were recruited on the basis of family history, mostly indicative of(More)
