Brief Summary:
Rapid Whole Genome Sequencing (rWGS) has proven to provide much faster diagnoses than traditional clinical testing, including clinical Whole Exome Sequencing (WES) and standard Whole Genome Sequencing (WGS). This collaborative study seeks to provide rWGS as a research test to additional pediatric hospitals nationwide to assist in the rapid diagnosis of acutely ill children suspected of a genetic condition. The study will examine diagnosis rates, changes in clinical care as a result of a genetic diagnosis, and health economics including potential cost-effectiveness of rWGS. This study will also serve as a biorepository for future research on samples and data generated from genomic sequencing.

Arm Intervention/treatment
Experimental: Enrollees
Enrollment of healthy and affected subjects to collect samples and data for a pediatric genomic biorepository. Data includes genomic sequencing and resultant molecular diagnostic results, if any.
Genetic: Genomic sequencing and molecular diagnostic results, if any
Samples will be stored in the pediatric genomic biorepository. A subset of samples will undergo genetic/genomic analysis.
Other Names:
  • Pediatric Genetic Biorepository
  • Pediatric Precision Medicine

Primary Outcome Measures :
  1. Number of samples enrolled per year [ Time Frame: Yearly through study completion estimated to be 40 years. ]
    Establishment of a biorepository for genomic/precision medicine use in pediatric population. This will make samples available to study rare genetic disorders, screening methods, diagnostic methods, other "omics," and bench research for possible treatments.

Secondary Outcome Measures :
  1. Proportion of children receiving molecular diagnoses [ Time Frame: Through study completion estimated to be 40 years. ]
    Utilize cutting edge technologies to improve both diagnostic rates and time to diagnosis for rare genetic diseases. Symptom driven return of results and analysis of clinical utility.

  2. Time taken to receive molecular diagnosis [ Time Frame: From date of enrollment until the date of documented clinical laboratory diagnosis or date of death from any cause, whichever came first, assessed up to 10 years. ]
  3. Proportion of children in which human phenotype ontology (HPO) terms accurately predict molecular diagnosis [ Time Frame: Through study completion estimated to be 40 years. ]
  4. Subject's main provider's perceived clinical utility of genomic sequencing [ Time Frame: Within one month of the return of results. ]
    Perceived utility/benefit of sequencing based on "Clinician Assessment" scale completed by patient's providers.

  5. Comparing diagnostic rates between singleton and trio analysis [ Time Frame: Within 30 days of enrollment. ]
    Marginal increase in diagnostic yield above singleton analysis based on the number of clinically confirmed diagnoses posted in medical record following singleton and trio levels of analysis in cases when both biological parents are available.

Ages Eligible for Study:   Child, Adult, Older Adult
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • The Repository will be comprised of samples from symptomatic patients, individuals reported to be their (symptomatic or asymptomatic) biologic family members, and control individuals. In this context a "symptomatic patient" is characterized as a patient whose treating physician has identified phenotypic features and/or signs of illness potentially attributable to a genetic disorder (also referred to as "Affected" or "Proband"). There will be no age, gender, race, or health restrictions for this Biorepository Study. However, since this study will be performed at children's hospitals and since genetic disorders are more likely to be present in children less than 4 months of age these cases will likely be preferentially enrolled. Preference will also be given to those who are acutely ill, suspected of a genetic condition, and for whom a diagnosis may result in change of clinical management.

Exclusion Criteria:

  • Participants will be excluded if they are unwilling to consent to research.

A patient may be determined ineligible if there is a prior diagnosis that explains their clinical presentation, if other traditional clinical genetic testing is more appropriate at the time of referral, if the clinical presentation is insufficient at the time of referral to suggest a genetic etiology, if the parents are unable or unwilling to provide permission for participation, if child protective services is involved in the case unless the child's life is in immediate danger and research holds out a prospect of direct benefit that is important to the health or well-being of the child and is available only in the context of the research in which case permission will be obtained from the party legally responsible for medical decisions.
