The Saami are regarded as extreme genetic outliers among European populations. In this study, a high-resolution phylogenetic analysis of Saami genetic heritage was undertaken in a comprehensive context, through use of maternally inherited mitochondrial DNA (mtDNA) and paternally inherited Y-chromosomal variation. DNA variants present in the Saami were(More)
Breast cancer is the most common cancer among women. To date, 22 common breast cancer susceptibility loci have been identified accounting for ∼8% of the heritability of the disease. We attempted to replicate 72 promising associations from two independent genome-wide association studies (GWAS) in ∼70,000 cases and ∼68,000 controls from 41 case-control(More)
BACKGROUND Data for multiple common susceptibility alleles for breast cancer may be combined to identify women at different levels of breast cancer risk. Such stratification could guide preventive and screening strategies. However, empirical evidence for genetic risk stratification is lacking. METHODS We investigated the value of using 77 breast(More)
The 6q25.1 locus was first identified via a genome-wide association study (GWAS) in Chinese women and marked by single nucleotide polymorphism (SNP) rs2046210, approximately 180 Kb upstream of ESR1. There have been conflicting reports about the association of this locus with breast cancer in Europeans, and a GWAS in Europeans identified a different SNP,(More)
François Jacob, in his brilliant 'The possible and the actual' (Jacob 1982), reminds us that 'scientific investigation begins by inventing a possible world, or a small piece of a possible world'. One may add that the space allowed for the possible is likely to be in strong positive correlation with the level of our ignorance. What chance, then, when(More)
Recently, a locus on chromosome 6q22.33 (rs2180341) was reported to be associated with increased breast cancer risk in the Ashkenazi Jewish (AJ) population, and this association was also observed in populations of non-AJ European ancestry. In the present study, we performed a large replication analysis of rs2180341 using data from 31,428 invasive breast(More)
Inherited mutations in PALB2 are known to be associated with increased breast cancer risk. We aimed to investigate the prevalence and risk association of a recurrent PALB2 mutation, c.509_510delGA, among 3,924 unselected breast cancer patients from Belarus, Russia or Germany. High-resolution melting analyses and direct sequencing identified the(More)
The ERCC4 protein forms a structure-specific endonuclease involved in the DNA damage response. Different cancer syndromes such as a subtype of Xeroderma pigmentosum, XPF, and recently a subtype of Fanconi Anemia, FA-Q, have been attributed to biallelic ERCC4 gene mutations. To investigate whether monoallelic ERCC4 gene defects play some role in the(More)
Multiple recent genome-wide association studies (GWAS) have identified a single nucleotide polymorphism (SNP), rs10771399, at 12p11 that is associated with breast cancer risk. We performed a fine-scale mapping study of a 700 kb region including 441 genotyped and more than 1300 imputed genetic variants in 48,155 cases and 43,612 controls of European descent,(More)
A nonsense mutation, p.Q548X, in the BLM gene has recently been associated with an increased risk for breast cancer. In the present work, we investigated the prevalence of this Slavic founder mutation in 2,561 ovarian cancer cases from Russia, Belarus, Poland, Lithuania or Germany and compared its frequency with 6,205 ethnically matched healthy female(More)
