The BRCA2 gene is associated with autosomal dominant hereditary breast and ovarian cancer (HBOC) syndrome (MedGen UID: 151793) and autosomal recessive Fanconi anemia, type D1 (FA-D1) (MedGen UID: 325420).

The penetrance of BRCA2 was estimated by maximizing the LOD score in BRCA2-mutation families, over all possible penetrance functions. The estimated cumulative risk of breast cancer reached 28% (95% CI 9%-44%) by age 50 years and 84% (95% CI 43%-95%) by age 70 years. Order this gene as a single gene test. BRCA2: Sequence analysis includes +/- 20 base pairs of adjacent intronic sequence.

In 2 brothers who both developed Wilms tumor and brain tumors, Reid et al. (2005) identified 2 truncating BRCA2 mutations (600185.0027; 600185.0031). In 51 Wilms tumors tested for both gene copy alterations and intragenic mutations, Rivera et al. (2007) found inactivation of the WTX gene (300647) in approximately one-third.

4. The RAD51 gene provides instructions for making a protein that is essential for repairing damaged DNA. Breaks in DNA can be caused by natural and medical radiation or other environmental exposures, and also occur when chromosomes exchange genetic material in preparation for cell division. Background Germline loss-of-function mutations in PALB2 are known to confer a predisposition to breast cancer. However, the lifetime risk of breast cancer that is conferred by such mutations remain Petrucelli N, Daly MB, Pal T.

Mutations of BRCA1/2 genes greatly increase lifetime risk to develop breast and ovarian cancer and these Inheritance of one defective copy of either of the two breast-cancer-susceptibility genes, BRCA1 and BRCA2, predisposes individuals to breast, ovarian and other cancers. Both genes encode very large protein products; these bear little resemblance to one another or to other known proteins, and their precise biological functions remain uncertain. Case report: A 65-year-old woman diagnosed with HBOC harboring BRCA2 mutations was found to have multiple tumors in the stomach and small intestine by abdominal screening. All tumors were resected, and KIT gene mutations (p.Trp557Leu and p.Lys558Glu) in exon 11 were detected in all tumors and peripheral blood leukocytes. PubMed GeneCards Summary for BRCA2 Gene: BRCA2 (breast cancer 2, early onset) is a protein-coding gene. Diseases associated with BRCA2 include fanconi anemia, complementation group d1, and breast-ovarian cancer, familial, 2. GO annotations related to this gene include histone acetyltransferase activity and single-stranded DNA binding.
