I have had Raynaud’s Primary since birth. My father who was a Nurse Practitioner (now retired) has also had Primary Raynaud’s since birth. I have one sibling who also has Raynaud’s. Both my father and I have participated in Raynaud’s clinical research studies. I doubt either one of us has been told that we have a genetic condition, however, isn’t it obvious if there are multiple people with it in the family and it was definitely carried with a paternal gene in this case. Neither my sibling or I have any children. Am I eligible to participate in this survey?
