My daughter was just dianosed with Noonan’s or CFC syndrome associated with the KRAS gene. I am looking to find people that have the same strain.

There is a fourth gene - RAF1

Perhaps this is a relatively new location? Our daughter’s DNA test came back with this location as the source of her disorder.
