BRCA1 and BRCA2
Genes whose mutations significantly raise the risk of breast and ovarian cancers.
What it is
BRCA1 and BRCA2 are genes that help our bodies repair damaged DNA. When these genes have mutations, it can lead to a higher risk of breast and ovarian cancers. Think of these genes like a repair crew that fixes mistakes in our DNA; if they're not working properly, those mistakes can cause problems.
How it works
In the body, BRCA1 and BRCA2 genes help fix damaged DNA by repairing breaks in the genetic material. When these genes are mutated, the repair process can be disrupted, leading to genetic instability and an increased risk of cancer. In a clinical setting, testing for BRCA1 and BRCA2 mutations can help identify people who may be at higher risk and guide their cancer screening and prevention strategies.
Why it matters
Understanding BRCA1 and BRCA2 is important for people who may be at higher risk of breast and ovarian cancers. Knowing whether someone has a BRCA1 or BRCA2 mutation can help them make informed decisions about their cancer screening and prevention options, such as increased surveillance or preventive surgery. This knowledge can also help researchers better understand the underlying causes of these cancers and develop more effective prevention and treatment strategies.
