ClinConnect Summary

This is an observational study to understand if the use of whole genome sequencing (WGS) increases the speed to diagnosis and how clinical management is changed in an intensive care population of neonates. This project utilizes approved genome sequencing methods at CLIA-certified facilities.

1. Neonate subjects who are eligible and whose parents consent to the study will undergo blood sample which will be sent for WGS and bioinformatics analysis, filtering first with a targeted panel of 1722 genes most likely to cause genetic disorders in the first year of life, and then with a whole exome...

Eligibility criteria

• Inclusion Criteria:
• * Neonates: In order to be approached to participate, a neonate must meet all of the following criteria:
• • 1. Greater than 24 weeks gestational age
• • 2. Birth weight greater than 600 grams
• • 3. Admitted to the intensive care unit at UPMC Children's Hospital (CHP) and/or Magee Women's Hospital
• • 4. Possibility of a genetic disorder based on signs, symptoms, and laboratory values triggering a formal clinical medical genetics consult by the clinical care team.
• • 5. Triaged by PI or attending co-investigators and prioritized to introduction of this research study based on patient-specific clinical concerns
• • 6. Documented informed consent from parent/guardian
• • Parents: Parent of a neonate who meets the above inclusion criteria and who has been consented to participate in the study.
• • Siblings: Siblings of a neonate who meets the above inclusion criteria and who has been consented to participate in the study. Siblings will only be recruited if their participation has been determined to be essential to the accurate interpretation of the neonate's genetic studies.
• • Historical Controls: Individuals who have been evaluated by Medical Genetics within the last 24 months and who meet the criteria for matched controls as defined by propensity score matching.
• Exclusion Criteria:
• * Neonates: An individual who meets any of the following criteria will be excluded from participating in this study:
• • 1. Has a known etiologic diagnosis (e.g. prenatal testing)
• • 2. Has a major congenital anomaly (renal, cardiac, hepatic, neurological, or pulmonary malformations) associated with a chromosomal anomaly detected on prenatal testing (e.g. ultrasound, genetic testing)
• • 3. Sequencing sent after birth for any other reason than the genetics consult that triggers the study
• • 4. Presence of documented significant congenital infection (e.g. congenital cytomegalovirus)
• * Parents:
• • 1. Is not the biological parent of the identified neonate
• • 2. There is no exclusion for parent participation. If the parent is less than 18 years of age, however, these individuals will be asked to assent to the study and their parent(s) will be asked to provide permission/consent for the minor parent's participation
• • 3. Having had previous genetic testing does not exclude the parent from participating in this study.
• * Siblings:
• • 1. Is not a biological sibling of a neonate who meets the inclusion criteria
• • 2. Is not require for accurate interpretation of neonate results
• • 3. Having had previous genetic testing does not exclude the sibling from participating in this study.
• • Historical Control: Has not been seen within the past 24 months and/or does not meet the criteria for matched control as defined by propensity score matching. Part of this matching requires that the historical control be matched to a study participant based on age, thus they will be selected based on all matching criteria and will be excluded if they do not meet the criteria, including age.
