- Common name
- BRCA1, DNA repair associated
- Description
- This gene encodes a nuclear phosphoprotein that plays a role in maintaining genomic stability, and it also acts as a tumor suppressor. The encoded protein combines with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein complex known as the BRCA1-associated genome surveillance complex (BASC). This gene product associates with RNA polymerase II, and through the C-terminal domain, also interacts with histone deacetylase complexes. This protein thus plays a role in transcription, DNA repair of double-stranded breaks, and recombination. Mutations in this gene are responsible for approximately 40% of inherited breast cancers and more than 80% of inherited breast and ovarian cancers. Alternative splicing plays a role in modulating the subcellular localization and physiological function of this gene. Many alternatively spliced transcript variants, some of which are disease-associated mutations, have been described for this gene, but the full-length natures of only some of these variants has been described. A related pseudogene, which is also located on chromosome 17, has been identified. [provided by RefSeq, May 2009]

Significant/Non-significant: 0/1
- Longevity Association
- Non-significant
- Population
- American (Caucasians) and Italian
- Study Design
- Polymorphisms were examined in 102 centenarians from the New England area and 84 centenarians from Italy. The control population consisted of 97 individuals from Italy.
- Conclusions
- The genotype a+a was more frequent in both centenarian groups compared to the control group whereas the genotype a+b was less frequent. The results however were not statistically significant.
