This is a condition that makes a not in the hand that draws on the ring finger and pinkie finger curling your hand. It is inhiered? It usually dosen't happen till you are in your 60's. I do not know of anyone in my family that has ever had this. The Doctor said maybe someone has had but not as bad as mine and never did anything about it. I really don't know any Tubbs other than my family here in California. Do any of you know of this condition. The Doctor said it's mostly people from Wales
