OPMD is not “caught” like the flu or a cold. It is genetic and is comes from a mother and/ or a father. The percentage does not appear to be greater if both parents are carriers of OPMD. Most cases indicates that children will have about a 50/50 chance of seeing OPMD later in life. It is also shown that if a child of a parent or parents with OPMD, the child does not have it, the grandchildren will be OOMD free
