Common origins of BRCA1 mutations in Canadian breast and ovarian cancer families

TLDR
This article identified BRCA1 mutations in 12 of 30 (40%) Canadian families with breast and/or ovarian cancer, including six of the eight families (75%) that contained two cases of early-onset breast cancer.
Abstract
Women who carry mutations in the BRCA1 gene on chromosome 17q have an 85% lifetime risk of breast cancer, and a 60% risk of ovarian cancer. We have identified BRCA1 mutations in 12 of 30 (40%) Canadian families with breast and/or ovarian cancer, including six of the eight families (75%) that contained two cases of early-onset breast cancer and two cases of ovarian cancer. Six frameshift mutations account for all 12 mutant alleles, including nucleotide insertions (two mutations) and deletions (four mutations). Four independent families carried the same 1 basepair (bp) insertion mutation in codon 1755 and four other families shared a 2 bp deletion mutation in codons 22-23. These families were not known to be related, but haplotype analysis suggests that the carriers of each of these mutations have common ancestors.

Association of BRCA1 with Rad51 in Mitotic and Meiotic Cells

TL;DR: Findings suggest a functional interaction between BRCA1 and Rad51 in the meiotic and mitotic cell cycles, which, in turn, suggests a role for BRC a1 in the control of recombination and of genome integrity.

A census of human RNA-binding proteins.

TL;DR: This work presents a census of 1,542 manually curated RBPs that are analysed for their interactions with different classes of RNA, their evolutionary conservation, their abundance and their tissue-specific expression, a critical step towards the comprehensive characterization of proteins involved in human RNA metabolism.

Cancer Incidence in BRCA1 Mutation Carriers

TL;DR: In carriers of BRCA1 mutations, the overall increased risk of cancer at sites other than breast and ovary is small and is observed in women but generally not in men.

BRCA1 and BRCA2 : 1994 and beyond

TL;DR: The discovery of the first gene associated with hereditary breast cancer, BRCA1, was anticipated to greatly increase the understanding of both hereditary and sporadic forms of breast cancers, and to lead to therapeutic and preventive breakthroughs.

Identification of a RING protein that can interact in vivo with the BRCA1 gene product.

TL;DR: This BRCA1–associated RING domain (BARD1) protein contains an N–terminal RING motif, three tandem ankyrin repeats, and a C-terminal sequence with significant homology to the phylogenetically conserved BRCT domains that lie near the C terminus of BRCa1.

Linkage of early-onset familial breast cancer to chromosome 17q21

TL;DR: Ch Chromosome 17q21 appears to be the locale of a gene for inherited susceptibility to breast cancer in families with early-onset disease, and genetic analysis yields a lod score of 5.98 for linkage of breast cancer susceptibility to D17S74 in early-ONSet families and negative lod scores in familiesWith late-onsets disease.

Genetic linkage analysis in familial breast and ovarian cancer: results from 214 families. The Breast Cancer Linkage Consortium.

TL;DR: The results suggest that a gene(s) on chromosome 17q accounts for the majority of families in which both early-onset breast cancer and ovarian cancer occur but that other genes predisposing to breast cancer exist.
