Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description: BRCA2 is an important protein in cellular responses to DNA damage and may be directly involved in DNA repair. Mice deficient for BRCA2 have a reduced lifespan, though it is not clear whether they age faster [475]. Cells from human patients with mutations in BRCA2 exhibited reduced rates of DNA repair and elevated levels of protein ADP-ribosylation. These patients demonstrate motor apraxia, axonal neuropathy, and progressive cerebellar ataxia. Deletion of PARP1 in BRCA2-null mice partially reversed some of these effects [4487]. Although BRCA2's role in cancer is clear [1676], elucidating its role in human ageing will require additional studies.
