Trial Summary

Will I have to stop taking my current medications?

The trial does not specify whether participants need to stop taking their current medications. Since the study involves newborns, it is unlikely that parents need to change their medication routines.

What data supports the effectiveness of the treatment Genome sequencing-based newborn screening?

Research shows that rapid whole-genome sequencing (rWGS) can identify genetic disorders in newborns with high accuracy, detecting 87% of diagnoses previously made by traditional methods and finding additional cases not caught by conventional screening. This approach could potentially prevent symptoms in critically ill children if interventions are started early.12345

Is genomic screening for newborns safe?

Genomic screening for newborns, such as whole genome sequencing, is being explored in several trials and has shown promise in accurately diagnosing genetic conditions early. However, there are ongoing discussions about its safety, ethical, and legal implications, and more evidence is needed to fully understand its benefits and risks.12678

How does genomic newborn screening differ from other treatments for rare genetic conditions in newborns?

Genomic newborn screening is unique because it uses whole genome sequencing to identify almost all genetic disorders in newborns before symptoms appear, allowing for early intervention. This approach is more comprehensive than traditional newborn screening, which typically tests for a limited number of conditions by measuring blood metabolites.178910

What is the purpose of this trial?

The goal of this study is to learn how genomic sequencing technology can be used to effectively expand the conditions screened on newborn screening. Newborn screening ensures equity and allows all babies to have the same chance at the healthiest life. Families will be invited to have their newborn baby screened for additional conditions beyond what all babies are screened for as part of the newborn screening public health program. Families can choose to be part of the study or choose not to be part of the study and just have the routine newborn screening test. Families will also be able to choose to learn about their baby's risk for conditions that have effective treatments available but are not on the routine newborn screening panel or also learn about conditions for which there is not currently FDA approved medications but for which medications are under development or for which early intervention services or treatment of seizures may improve the child's outcome. Families will be invited to the study shortly after the baby is born and will learn the decision not to participate, and we will interview a subset of parents who agree to be interviewed. Newborns who screen positive will be referred to appropriate providers for care and will be followed through review of electronic medical records and parental follow up via phone, text, postal mail or email.

Eligibility Criteria

This trial is for newborns in well-baby nurseries from certain hospitals, born after 33 weeks of gestation. It's open to babies whose parents speak English, Mandarin, or Spanish. The study aims to screen these babies for additional rare genetic conditions beyond the standard public health screenings.

Inclusion Criteria

Newborns admitted to the well-baby nurseries from the recruiting hospitals
Newborns whose parents are English, Mandarin, or Spanish speaking
My baby was born after 33 weeks of pregnancy.

Findings from Research

Rapid whole-genome sequencing (rWGS) for newborn screening (NBS) can identify a wide range of genetic disorders, with a high sensitivity of 88.8% and a negative predictive value of 99.6%, making it a promising tool for early diagnosis and intervention.
In a simulated study involving over 454,000 subjects, rWGS could have potentially prevented symptoms in critically ill newborns by diagnosing conditions that conventional NBS missed, highlighting its effectiveness in improving outcomes for genetic diseases.
A genome sequencing system for universal newborn screening, diagnosis, and precision medicine for severe genetic diseases.Kingsmore, SF., Smith, LD., Kunard, CM., et al.[2023]
Genomic sequencing can significantly enhance newborn screening programs by enabling rapid and accurate diagnoses of treatable rare diseases, which are major contributors to infant mortality and lifelong disabilities.
As large-scale genomic screening projects begin globally, it is crucial to generate evidence of their benefits while also addressing ethical, legal, and psychosocial challenges associated with this technology.
Genomic newborn screening for rare diseases.Stark, Z., Scott, RH.[2023]
A significant majority (87.9%) of rare disease experts support the use of newborn genome sequencing (NBSeq) to identify treatable monogenic disorders in all newborns, highlighting its potential to improve early detection and treatment.
Experts recommended including 25 specific genes associated with treatable conditions in NBSeq, with 42 gene-disease pairs endorsed by at least 80% of respondents, indicating a strong consensus on which conditions should be prioritized for screening.
