The Breast Cancer Susceptibility Genes, BRCA1 and BRCA2, are the dynamic regulators of genomic integrity. Inherited mutations in these genes are associated with the development of cancer in multiple organs including the breast and ovary. Mutations of BRCA1/2 genes greatly increase lifetime risk to develop breast and ovarian cancer and these

Heterozygous mutations of BRCA2 cause susceptibility to breast and ovarian cancer (see OMIM), a phenotype that is not appropriate for our purposes. Homozygous mutations of BRCA2 cause Fanconi anemia (see GeneReviews), which is an appropriate phenotype but is …

GeneReviews®. Seattle (WA); 1993. 4. Ursächlich für den erblichen Brust- und Eierstockkrebs sind vor allem genetische Veränderungen (Mutationen) in den Genen BRCA1 und BRCA2. Daneben werden allerdings zunehmend mehr Gene identifiziert (u.a. CHEK2, PALB2, RAD51C), die ebenfalls zu einem erhöhten Risiko für Brustkrebs und zum Teil andere Tumore führen, aber wesentlich seltener betroffen sind.

BRCA1 - and BRCA2 -associated HBOC syndrome is often characterized by early age of cancer onset (typically before 50 years of age) and multiple, multifocal, and/or similar cancers in a single individual or in a closely related family member(s). Overall, disease was linked to BRCA1 in an estimated 52% of families, to BRCA2 in 32% of families, and to neither gene in 16% (95% confidence interval [CI] 6%-28%), suggesting other predisposition genes. The majority (81%) of the breast-ovarian cancer families were due to BRCA1, with most others (14%) due to BRCA2. GeneCards Summary for BRCA2 Gene: BRCA2 (breast cancer 2, early onset) is a protein-coding gene.

The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele. [provided by RefSeq, May 2020].

The BRCA2 gene provides instructions for making a protein that acts as a tumor suppressor. Tumor suppressor proteins help prevent cells from growing and dividing too rapidly or in an uncontrolled way.
