What are the chances my baby will have sickle cell disease (SCD)?

If both parents have sickle cell trait (SCT), there is a 50 percent (or 1 in 2) chance that the child also will have SCT, because there's a 50 percent chance the child will inherit the sickle cell gene from one of the parents. Such children will not have symptoms of sickle cell disease (SCD), but they can pass SCT on to their children.

If both parents have SCT, there is a 25 percent (or 1 in 4) chance that the child will have SCD. There is the same 25 percent (or 1 in 4) chance that the child will not have SCD or SCT. If one parent has SCT, there is a 50 percent (or 1 in 2) chance that the child will have SCT and an equal 50 percent chance that the child will not have SCT.
