Does BRCA2 affect fertility?
A growing number of biologists and geneticists have predicted that BRCA1 and BRCA2 gene mutations, which have been shown to produce elevated risks of breast and ovarian cancer, would also be associated with reductions in female fertility.
What is the life expectancy of someone with BRCA2?
Results. We calculated that, on average, 30-year-old women who carry BRCA1 or BRCA2 mutations gain from 2.9 to 5.3 years of life expectancy from prophylactic mastectomy and from 0.3 to 1.7 years of life expectancy from prophylactic oophorectomy, depending on their cumulative risk of cancer.
Who inherits the BRCA2 gene?
Everyone has two copies of the BRCA1 and BRCA2 genes, one copy inherited from their mother and one from their father.
How serious is the BRCA2 gene?
When a mutation damages either of these genes, the person’s risk of cancer increases. Inheriting damaged copies of the BRCA1 or BRCA2 genes can increase the risk for breast cancer and ovarian cancer in women and the risk for breast and prostate cancer in men, as well as other cancers.
Should I have kids if I have BRCA mutation?
The family planning options for men and women with a BRCA1 or BRCA2 mutation are: To have children without any intervention – each child would have a 50 per cent chance of inheriting the mutation. To not to have children at all.
Can I have kids with BRCA gene?
There are a few possible outcomes if both parents carry a BRCA1/2 gene mutation: There is a one in two chance that your child will inherit a single BRCA1/2 gene mutation and a one in four chance that your child will not inherit any BRCA1/2 gene mutation at all.
Does BRCA2 skip a generation?
If you have a BRCA mutation, you have a 50 percent chance of passing the mutation to each of your children. These mutations do not skip generations but sometimes appear to, because not all people with BRCA mutations develop cancer. Both men and women can have BRCA mutations and can pass them onto their children.
What if I have BRCA2 gene?
A positive test result means that you have a mutation in one of the breast cancer genes, BRCA1 or BRCA2, and therefore a much higher risk of developing breast cancer or ovarian cancer compared with someone who doesn’t have the mutation. But a positive result doesn’t mean you’re certain to develop cancer.
Can the BRCA2 gene skip a generation?
Should you get a mastectomy if you have the BRCA2 gene?
Prophylactic mastectomy can reduce the chances of developing breast cancer in women at high risk of the disease: For women with the BRCA1 or BRCA2 mutation, prophylactic mastectomy reduces the risk of developing breast cancer by 90 to 95 percent.
Can my daughter have the BRCA gene if I don t?
BRCA mutations can be a family matter
If 1 parent has a BRCA mutation, all of his or her children have a 50% chance of inheriting that mutation. Even if a child inherits only 1 mutated BRCA gene, that person’s risk of developing cancer increases.
Can BRCA gene skip a generation?
Does BRCA skip a generation?
What should I do if I test positive for BRCA?
If you are a man with a BRCA1 or BRCA2 mutation, your doctor may recommend the following: Breast self-exam training and education starting at age 35. Yearly clinical breast exams starting at age 35. Prostate cancer screening starting at age 45, especially for men with a BRCA2 mutation.
What does it mean if you test positive for the BRCA2 gene?
A positive test result indicates that a person has inherited a known harmful variant in BRCA1 or BRCA2 (these are typically called “pathogenic” or “likely pathogenic” variants on laboratory test reports) and has an increased risk of developing certain cancers.
What if you are BRCA2 positive?
What cancers does BRCA2 cause?
The most commonly reported cancers with BRCA2 mutations include pancreas, prostate, and melanoma.
What is worse BRCA1 or BRCA2?
Which Gene Mutation is Worse, BRCA1 or BRCA2? By age 70, women BRCA1 carriers have a slightly higher risk of developing breast cancer than BRCA2 carriers. Also, BRCA1 mutations are more often linked to triple negative breast cancer, which is more aggressive and harder to treat than other types of breast cancer.
