Why does GeneDx recommend trio testing (testing the patient plus two biological relatives, such as mother and father) for exome and genome sequencing?

The diagnostic rate is highest when a trio is submitted and analyzed, as the inclusion of parental data improves the ability to classify variants. The absence of parental data may lead to higher rates of variants of unknown significance that could otherwise be dismissed based on inheritance patterns.
