Table 1. Potential Prenatal Testing Categories.

Type of information	Does it inform reproductive decision-making for current pregnancy?	Might the future child have an interest in not knowing the information?	Could it provide immediate benefit to the future child?
Variants of unknown significance (genetic variations whose association with disease risk is unknown)	No	Yes	No
Nonmedical genetic markers (genetic variations that have no health-related significance)	No	Yes	No
Carrier status (possession of genetic variations that do not cause illness in the carrier but might contribute to illness in the carrier's offspring)	No	Yes	No
Susceptibility genes (genes with variants that indicate increased likelihood for developing a condition)	Sometimes	Yes	No
Late onset genetic conditions (highly penetrant genetic conditions that display no symptoms until late in life)	Sometimes	Yes	No
Medical conditions found by current prenatal genetic tests (conditions with 100 percent penetrance that seriously affect health and quality of life throughout the life cycle)	Yes	NA	Sometimes
