Important Information

This test is an option for patients who have had previous exome or genome testing at another clinical laboratory and where results may not have explained the patient’s condition or where a second opinion by GeneDx is wanted. For optimal results, exome sequencing will be repeated from a new sample, not just reinterpretation of previous data. This test can be performed on a singleton, duo, or trio. A new sample and a copy of the previous report are required to initiate testing.
