A member asked:

My son has the sickle cell trait and neither his father or me have the trait. this is confirmed. how is this possible please?

A doctor has provided 1 answer

New mutation: i am going to assume that a real lab study has confirmed this by hemoglobin electrophoresis and this is not a sample switch, tech error, or other cause of a bad result. Since Junior is going to ask questions, I would urge for the family's sake to do the genetic studies to confirm paternity. You are brave to ask. Best wishes.
