Overview
Brief Summary
The goal of this clinical trial is to test a new method for newborn screening using whole genome sequencing, called BeginNGS. Newborns who are not suspected of having genetic diseases and who are admitted to the NICU at Rady Children's Hospital, San Diego, will be enrolled. The main questions this study aims to answer are:
- What is the diagnostic yield of diagnostic whole genome sequencing (DWGS) in this population?
- What is the diagnostic sensitivity and specificity of BeginNGS and whole exome sequencing (WES) as compared to DWGS?
- What are the potential issues related to implementing DWGS in this population?
Enrolled newborns will have a blood sample taken and will receive three tests:
- DWGS
- BeginNGS
- WES
Detailed Description
Newborn screening (NBS) by testing dried blood spots (DBS) identifies newborns with a few diseases for which effective treatments are available to enable treatment at or before symptom onset. Because NBS improves outcomes in these diseases, it is performed on almost all US babies. The current Federal recommended NBS list is limited to 35 conditions and identifies \~6,600 affected children per year. In genetic diseases not screened by NBS, however, outcomes remain poor because of delays in diagnosis and treatment. The investigators recently developed a system for NBS for 434 severe, childhood genetic diseases for which effective treatments are available using whole genome sequencing (WGS), called BeginNGS. Retrospective studies showed BeginNGS to have a true negative rate (specificity) of 99.7% and true positive rate (sensitivity) of 88.8%. The investigators now propose to undertake a first prospective study in newborns admitted to the Neonatal Intensive Care Unit (NICU) at Rady Children's Hospital, San Diego (RCHSD) to compare the sensitivity and specificity of BeginNGS with that of standard, diagnostic rapid whole genome sequencing (DWGS) and whole exome sequencing (WES). This study is in preparation for larger, future clinical trials.
