GeneticsCancer biology
Quick Answer
The BRCA1 gene is located on chromosome 17. It helps repair damaged DNA and is linked to hereditary breast and ovarian cancer risk.
The Full Story
BRCA1 is found on the long arm of chromosome 17 in the human nuclear genome. It produces a tumor-suppressor protein involved in DNA repair, especially double-strand break repair. Inherited harmful variants can greatly increase the risk of breast and ovarian cancer. Genetic testing for BRCA1 and BRCA2 is widely used in cancer risk assessment and prevention planning.
Key Facts
1.Located on chromosome 17
2.Acts as a tumor suppressor
3.Inherited variants can raise cancer risk
