What Do Brca1 And Brca2 Stand For
This is a normal gene that makes a protein for basic cell functions. It was the second gene discovered that is often mutated in people at extra risk for breast cancer, and depending on the mutation these people often have increased risk of ovarian cancer as well. A person with a family history may be tested for the mutation and make ...Read more
No: The penetrance of a mutation defines the risk of developing the disease in those that carry a particular mutation. Women with brca mutations have lifetime risks estimated between 40-80%; men's risks are much less-studied but are probably in the range of 10% or less. ...Read moreSee 1 more doctor answer
Breast cancer genes: "BR" stands for breast "CA" stands for cancer In the mid-1990s, two genes were found that are changed in many families with breast cancer. The first gene found was named BRCA1 (BReast CAncer first gene found) and the second one was named BRCA2. The search for other genes continues. ...Read moreSee 1 more doctor answer
Know risk factors!: Genetic testing is recommended for: 1)a personal history of breast cancer at age 50 or younger 2)a personal history of triple negative breast cancer (breast cancer that is estrogen receptor-negative, Progesterone receptor-negative and her2/neu receptor-negative) 3)a personal or family history of male breast cancer 4)a personal or family history of bilateral breast cancer 5)history of ovarian cance. ...Read moreSee 1 more doctor answer
Genetic counseling: The penetrance of a mutation defines the risk of developing the disease that one is at risk for. The penetrance of the brca mutations varies between 40-80% for women and less than 10% for men, depending on the specific mutation and patient factors. The best method to prevent breast cancer at this time is to have a prophylactic bilateral mastectomy. ...Read moreSee 2 more doctor answers
Clarifying Q & A: In the general population, the incidence of a brca1 mutation is between 1:500 to 1:800. It is much lower for brca2. For a woman or offspring to inherit the gene from a parent who has one copy of the mutated gene, there is a 50% chance of acquiring the gene in question. It is autosomal dominant and therefore can manifest its deleterious consequences by itself without need of a second copy. ...Read more
Brac1 and brac2 gene: No nobody keeps track of that because these tests are done all over the world. ...Read more
Yes: Brca1 and 2 mutation analysis is performed at myriad lab in usa. One can either use an oral swab or blood for testing. It is strongly recommended that the testing is done in the context of genetic counseling as the interpretation of the test and risk assessment for breast/ovarian cancer are complex and requires professional explanations. ...Read moreSee 1 more doctor answer
Very high risk: Patients who are brca positive have a very high risk of developing breast cancer. They can have an 80-90% risk (over lifetime) of developing 1 breast cancer, 50-65% chance of developing a 2nd breast cancer and a 40-50% risk of developing ovarian cancer.
