BRCA1 mutation is a genetic alteration in the BRCA1 gene that increases the risk of developing breast and ovarian cancer. Individuals with a BRCA1 mutation have an increased likelihood of developing these types of cancer compared to those without the mutation. Testing for BRCA1 mutations can help in assessing cancer risk and guiding management options.
Yes, BRCA1 is a tumor suppressor gene.
Yes, BRCA1 is considered a tumor suppressor gene, not an oncogene.
The inheritance pattern of the BRCA1 gene is dominant.
The gene BRCA1 helps repair damaged DNA in cells, which can prevent the growth of abnormal cells that could lead to breast cancer. Mutations in the BRCA1 gene can increase the risk of developing breast cancer because the cells may not be able to repair DNA damage properly.

BRCA1 and BRCA2 are genes that can mutate into cancer.
Breast cancer, as all cancers, is highly complex and caused by mutations in numerous genes - each cancer, however, will likely have different gene mutations.However, there are some genes which are commonly mutated in a small proportion of breast cancers (a mutation in these genes shows increased susceptibility in a number of families) - the most commonly referred to are BRCA1 and BRCA2.BRCA1 is found on 17q21 (chromosome 17, q arm, band 21) and BRCA2 on 13q12.
The gene BRCA1 helps repair damaged DNA in cells, which can prevent the growth of abnormal cells that could lead to breast cancer. Mutations in the BRCA1 gene can increase the risk of developing breast cancer because the cells may not be able to repair DNA damage properly.
yes
BRCA1 and BRCA2 are two genes in your DNA which when altered or mutated, leads to Breast cancer.
