It's All in the Family

Damn it.

Once my sister tested BRCA+, my mom got on the phone and reached out to a lot of family.  She wanted to let them know about the gene and their possible risks.  We were all aware that ovarian cancer preyed on women in our family; now, we were able to put a name to it: BRCA+.

Of course, it's not a given that every person in the family is BRCA+.

Here are some stats:

• Everyone has a BRCA gene.  This genes function is to suppress tumors.  If you have a mutated BRCA gene then your chance of suppressing certain tumors is reduced (hence the increased risk of breast, ovarian, and pancreatic cancers). 
• Because of my twin sister Jill, we knew my mom had to be BRCA(mutation)+.  The mutation doesn't 'skip' generations; It must come from a direct lineage.  From this information, we can also assume my maternal grandmother (she died in her early 40's from ovarian cancer) carried the mutation.  And likely, her mother, who also died of ovarian cancer.    
• Given that Jill and I are identical and have the same genes, I too am BRCA+.  If we were fraternal twins, it would have been a 50-50 chance.  
• My brother has a 50% chance of carrying the mutation.  I'm no geneticist, just ask my high school science teacher Mr. Devore).  The BRCA1 mutation is located on chromosome 17.  It depends which gene Josh inherited.  If he inherited Dad's normal BRCA gene, he is not a carrier.  If he inherited Mom's mutated BRCA gene, then he is a carrier.  
• My son has a 50% chance of carrying the mutation.  Again, if he inherited the gene from me, he is at risk, if he inherited the gene from his dad, Mason (and any offspring) will be in the clear. 
• As a reminder, both men and women can carry the BRCA mutation.  Due to the increased risk of breast and ovarian cancers, it affects women more, however men can definitely be carriers, and affected with increased risk of pancreatic and prostate cancers. 

I was so hoping other women on my mom's side of the family would be spared being BRCA+.  My cousin, Amy (who used to spend hours babysitting me and braiding my long, tangled hair until her fingers were numb) recently took the test.  Her dad (Mom's brother, my uncle) had a 50% chance of having the gene.  If he is positive, then Amy, too, has a 50% chance of having it.  Decent odds of her not having it, right (Note, I'm also no math wiz).  Unfortunately, Amy found out she, too, has the mutated gene.  Just an example of how this gene can definitely be passed down through the male side of the family.  In her words, "that gene is a strong son of a bitch." Nicely, and accurately stated, Amy.  

Amy has some big decisions to make.  There is not set path that you must follow.  And while that is a blessing, it's also a curse.  Since Amy is a Canote, decisions don't necessarily come easily (Grandpa Canote was a notorious worrier).  But, the Canote's are also strong, so I know she's going to be just fine.  Along with being a worrier, Grandpa Canote was also an extremely faithful man.  No doubt he is looking out for us (and probably worried if there is worry in Heaven, which isn't likely) on the other side.  

Love you, Amy.  Can't wait for my hair to be long enough for you to braid again, just for old times sake.
