The objective of this research protocol is to assess the impacts of genomic sequencing in healthy infants from ethnically and racially diverse communities as part of routine pediatric care.
Investigators will enroll a cohort of 500 healthy, ethnically and racially diverse infants from Boston, Massachusetts; New York City, New York; and Birmingham, Alabama, with planned expansion to other U.S. cities and recruitment sites. As part of this study, a stakeholder board comprised of diverse community members will provide early and regular feedback throughout the study on anticipated and ongoing community reaction to the work with sensitivity to historical injustices and cultural diversity
Primary care pediatricians from each recruitment site will be enrolled for a brief genomics education curriculum. Only infants whose healthcare providers have joined the study will be enrolled.
A small blood sample will be obtained from each enrolled infant. Participants will randomized (1:1) to receive either a family history report or a family history report plus whole genome sequencing.
Genome sequencing data will be analyzed for pathogenic and likely pathogenic variants in genes associated with childhood-onset disease risks, as well as highly actionable adult-onset disease risks. If infants have a dominant risk identified, parents may choose to be screened as part of the study.
The study team will disclose the infant's randomization status and study results during a consultation with each family, and results will be sent to the infant's pediatrician.
Parents will be surveyed at three time points over the 12 months after enrollment: baseline, immediately post-disclosure (approximately 3 months after enrollment), and 6 months post-disclosure. Surveys will assess psychosocial impacts of newborn sequencing.
Chart reviews will be performed to assess the medical outcomes and healthcare utilization costs of newborn genome sequencing.

---|---|
Experimental: Sequencing cohort
Infants receive genome sequencing with analysis of approximately 1000 genes associated with childhood-onset and highly actionable adult-onset disease risks. Pathogenic and likely pathogenic variants are reported to the child's parents and pediatrician. Participants also receive a detailed family history report and standard well-child care.

Genetic: Genome Sequencing
20 times read depth (20x) next-generation whole genome sequencing with comprehensive analysis. |
No Intervention: Control cohort
Infants receive a detailed family history report plus standard well-child care.
|
- Monogenic disease risks (MDRs) [ Time Frame: 3 months after enrollment ]Pathogenic (P) and likely pathogenic (LP) variants identified relevant to infant's health (dominant or biallelic recessive disease risks)
- Carrier status variants [ Time Frame: 3 months after enrollment ]P and LP variants identified as recessive carrier status in infant
- MDR-associated phenotype [ Time Frame: 3 months after enrollment and 1-year post-disclosure (15 months after enrollment) ]Signs or symptoms of monogenic disease risk identified by genome sequencing
- Parent-Child Relationship [ Time Frame: Baseline, post-disclosure (3 months after enrollment), 6 months post-disclosure (9 months after enrollment) ]Parenting Stress Index, 4th Edition Short Form (scored as a percentile 0 - 100%, higher scores indicate increased stress); Vulnerable Baby Scale (scored 0 -50, higher scores indicate increased perceptions of child vulnerability)
- Partner Relationship [ Time Frame: Baseline, post-disclosure (3 months after enrollment), 6 months post-disclosure (9 months after enrollment) ]Kansas Marital Satisfaction Scale (Scored 3 to 21, higher scores indicate better marital quality; Partner Blame (novel, higher scores indicate increased blame)
- Personal Distress [ Time Frame: Baseline, post-disclosure (3 months after enrollment), 6 months post-disclosure (9 months after enrollment) ]General Anxiety Disorder-7, Patient Health Questionnaire (PHQ)-9 , Self-Blame
- MDR-associated family history [ Time Frame: 3 months after enrollment and 1-year post-disclosure (15 months after enrollment) ]Signs or symptoms of monogenic disease risk or recessive condition present in infant's biological family
- Feelings about genomic testing [ Time Frame: Baseline, post-disclosure (3 months after enrollment), 6 months post-disclosure (9 months after enrollment) ]Feelings About genomiC Testing Results (FACToR) Questionnaire
- MDR-associated intervention [ Time Frame: 1-year post-disclosure (15 months after enrollment) ]Healthcare intervention prompted by monogenic disease risk or recessive carrier variant
- Suspected genetic condition [ Time Frame: 1-year post-disclosure (15 months after enrollment) ]Any phenotype that develops in an infant suspected to have a genetic cause, or any genetic testing ordered as part of clinical care
- Cost of attributable services [ Time Frame: 1-year post-disclosure (15 months after enrollment) ]Cost of healthcare services that were recommended for infants and parents as part of study disclosure session
- Cost of genomic services [ Time Frame: 1-year post-disclosure (15 months after enrollment) ]Cost of genetic services infants and parents received after study disclosure session
- All healthcare costs [ Time Frame: 1-year post-disclosure (15 months after enrollment) ]All health sector costs observed in medical records and survey questions regarding family out-of-pocket expenses
