I am a carrier of WAS. I have 3 children - 2 boys and a girl. My oldest son a very mild form of it. Mainly just has the small platelets. My youngest son has a more severe form. He had a little bit of an immune deficiency. My question is that if my daughter is a carrier, what are the chances of her passing it to her children if she has boys? I was told that it will skip a generation? Is that true? And also if we decide to have another child and it is a boy, I know there's a 50/50 chance he would get it, but would it be any worse than in my other 2 sons? See answer
