Exome Sequencing, Trio
Ordering Recommendation

Preferred test to determine etiology of a patient’s symptoms if Mendelian genetic condition is suspected. Parental specimens are required to identify de novo variants and interpret patient results; order Exome Sequencing, Familial Control, Tracking (2006340). 

Massively Parallel Sequencing
4-8 weeks
New York DOH Approval Status

Statement C: Compliance Statement C: For human genetic inheritable conditions and mutations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Counseling and informed consent are recommended for genetic testing. Consent forms are available online.

A completed Exome Sequencing consent form, signed by the patient (or legal guardian), and a completed patient history form for exome testing is required for all specimens. Samples should also be collected from both parents and any affected siblings and Exome Sequencing, Familial Control (ARUP Test Code 2006340) ordered to aid interpretation of patient's result. A separate patient history form should be completed for each control detailing their health history. For each parental or family member's specimen, please indicate on the test requisition form that the sample is a control and reference the patient's name.
