Ordering Recommendation

Whole genome sequencing (WGS) is the preferred test to establish a diagnosis when a genetic condition is suspected but the patient’s clinical features are not suggestive of a single disorder. Parental comparator specimens are recommended for this test; order Genome Sequencing, Familial Comparator (3019951). Submission of a completed Genome Sequencing Intake Form is required for the proband.

To compare this test to other exome/genome testing options, refer to the ARUP Genome and Exome Sequencing table.
