I’m the last

My sister-in-law told me yesterday my brother tested negative for the gene mutation.  All good news!  Yay, my brother and little nephew are in the clear!  I assumed that would be the case as I’ve read articles that it doesn’t normally pass on to males in families, but it’s good that my brother took my advice and got tested, to be on the safe side.  Now it won’t be passed on in our family’s genes.  I’m the last.
