BreastCancer.org says that the daughter of a woman who does NOT have the BRCA mutation doesn't need to be tested for the mutation, BUT couldn't the daughter have inherited a mutation from her father???  Just because a mother doesn't have the mutation doesn't guarantee that her daughter won't have the mutation, so testing might still be advisable....yes???  Please help clear up this confusion.  Thanks!

    Yes, she could have inherited it from her father (according to the genetic counselor that I saw).  However if all of the risk was from her mother's side of the family, the risk level from her father's side of the family may not rise to the level that would suggest that testing is advisable.

    HTH,

    Yes it can come from either parent.

    Note that nothing is said about maternal or paternal side only!

    Yes! My genetics doc said both my son and daughter need to be tested for the gene! It can come from either parent and is no more likely to come from one than the other.

    Sons? Yes for if they are positive, they have several concerns. They may pass this gene along to their children. Next, they (according to my doc) have a greater than normal chance of developing prostate cancer as well an melanoma. There are additional cancers which are"believed" to also be associated with this gene but the jury is still out of this.

    Hugs,
