Clustered DNA lesions, possibly induced by ionizing radiation, constitute a trial for repair processes. Indeed, recent studies suggest that repair of such lesions may be compromised, potentially leading to the formation of lethal double-strand breaks (DSBs). A complex multiply damaged site (MDS) composed of 8-oxoguanine and 8-oxoadenine on one strand,(More)
Numerous genetic factors that influence breast cancer risk are known. However, approximately two-thirds of the overall familial risk remain unexplained. To determine whether some of the missing heritability is due to rare variants conferring high to moderate risk, we tested for an association between the c.5791C>T nonsense mutation (p.Arg1931*; rs144567652)(More)
Breast Cancer is a complex multifactorial disease for which high-penetrance mutations have been identified. Approaches used to date have identified genomic features explaining about 50% of breast cancer heritability. A number of low- to medium penetrance alleles (per-allele odds ratio < 1.5 and 4.0, respectively) have been identified, suggesting that the(More)
Less than 20 % of familial breast cancer patients who undergo genetic testing for BRCA1 and BRCA2 carry a pathogenic mutation in one of these two genes. The GENESIS (GENE SISter) study was designed to identify new breast cancer susceptibility genes in women attending cancer genetics clinics and with no BRCA1/2 mutation. The study involved the French(More)
