Prospective, multi-site, study to evaluate the clinical utility of cWGS in a proband. One group will receive cWGS and a clinical report approximately 15 days after blood samples are received, while the other group will continue to receive standard of care until Day 60. The standard of care group will receive cWGS and a clinical report at Day 60 as part of secondary and tertiary analyses. Both groups will be followed for a total of 90 days.
This is a prospective, multi-site, randomized study to evaluate the clinical utility of cWGS in each proband. Throughout this study, each proband will receive SOC testing as determined by the site clinical team. Upon enrollment in the study, each proband will be randomly assigned to the 15 day cWGS group or the SOC group. SOC is defined as the management of the proband's care under the same or similar conditions as if the proband was not enrolled in this study. A blood sample from each enrolled proband will be collected and shipped to the Illumina Clinical Services Laboratory ("ICSL"), which is Clinical Laboratory Improvement Amendments (CLIA)-certified and College of American Pathologists (CAP)-accredited. ICSL will conduct cWGS testing with the TruGenome Undiagnosed Disease Test ("TruGenome Test"). The TruGenome Test cWGS results will be provided to the Principal Investigator (PI) or designee who will evaluate each proband test outcome based on the aggregate medical information, informed by the cWGS or SOC results.

Clinical Whole Genome Sequencing (cWGS) consists of the sequencing, analysis and interpretation of subjects samples and a return of the result to the ordering physician.

A difference in Change of Management between the 15 day cWGS and standard of care groups
Change of Management is a binary (yes or no) based on assignments made by the PI or designee at each site using the following domains: * Condition specific management * Condition specific supportive interventions * Palliative care/End of Life Care A change in any of these domains will be considered a change of management.

cWGS satisfaction questionnaire will be given to clinicians and families at the conclusion of the study.
The questionnaire is a likard scale questionnaire developed by the study team to assess satisfaction levels from the perspective of the clinician and also the parent.
