BRCA1 gene belongs to a class of genes known as tumor suppressor genes protein from the BRCA1 gene helps prevent cells from growing and dividing too rapidly
This gene produce a protein that is directly involved in repairing damaged DNA. In the nucleus of many types of normal cells, the BRCA1 protein interacts with several other proteins, including the proteins produced from the RAD51 and BARD1 genes, to mend breaks in DNA. These breaks 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. By helping repair DNA, BRCA1 plays a role in maintaining the stability of a cell's genetic information.
So if a mutation in BRCA1 occurs the breaks in DNA can't be fixed and response to cancer affected
