The father son is my uncle and cousin. There were 11 children in this family and 3 of the child have is, including my mom, myself and I am thinking one of my daughter's. I do nothing for mine, they do phlebotomy after phlebotomy on my mom except for the past two yrs. She had to be put on blood thinners and she has not had one since, levels have not been high, so we are all watching to see if this keeps working. All I do is not take anything with iron, have always been told no iron.
