Ah, BRCA1! Step inside a room & I will explain everything.
My sister called me and said that she has the BRCA1 gene. She told me that I shold get tested. What does that mean?
Hi! I'm Dr. Genetics. Let's take a closer look at what you have going on.
This is your DNA! DNA is your body's blueprint, & it controls EVERY gene in your body, from your hair color to whether or not you like cilantro!
I <3 DNA
Sometimes, genes will mutate and do things that they are not supposed to do. This can happen for several reasons. Sometimes, this trait can be passed down through families. Other times, environmental influences, like spending too much time in the sun without sunscreen, will cause genes to mutate.
The BRCA1 & BRCA2 genes in your DNA usually have the job of preventing tumors from forming by repairing damaged DNA. Sometimes, you can inherit a BRCA1 or BRCA2 gene mutation, in which the genes don't actually fix the damaged DNA like it should.
A BRCA1 or BRCA2 mutation can be inherited from your mother or father. Since your sister has a BRCA1 mutation, it is likely that she inherited it from one of your parents. This means that you may also have a BRCA1 mutation.
Women that have inherited a BRCA1 or BRCA2 mutation are at a higher risk for developing both breast and ovarian cancer. You should consider genetic testing to see if you also have the BRCA1 mutation. There are several treatment options you can pursue after genetic testing if you do have the gene.
Thank goodness I came in today, I can't wait to have my genes tested so I can stay healthy!
