In brief: If a child has Down
Since down syndrome babies are usually from new mutations, their trisomy 21 is not hereditary (meaning the parents are not carriers of a genetic defect).
However, in a few cases, down syndrome is hereditary (a parent has a translocation where his or her chromosome #21 has attached itself to another chromosome). If such a case is suspected, then the parents should get screened by genetics testing.
