But for families of babies born with a rare genetic disease, the story is one fraught with challenges on their journey to an accurate diagnosis and appropriate care.
BeginNGS is a novel health care delivery system designed to screen newborns for genetic diseases — and connect their doctors with effective interventions.
They may not appear until later in childhood; however, the effects may begin before symptoms manifest. The effects may be irreversible if not diagnosed and treated.
Other times, the baby can receive cutting-edge gene therapy and grow up to be a typical healthy child, like Fitz Kettler, pictured here.
BeginNGS is an RCIGM-led pilot that uses rapid whole genome sequencing (rWGS) as a screening tool for newborns, to identify genetic conditions before infants get sick. The BeginNGS pilot is not about replacing the current biochemical newborn screening approach (for roughly 60 known conditions) – rather, it is a complement to the newborn screening processes and infrastructure that are already in place.
Technological advances in rapid whole genome sequencing (rWGS) have made it possible to return test results in just a few days at a lower cost.
Since the whole genome is sequenced, the screening can be rapidly expanded to include new disorders as effective interventions become available.

There are over 30 million rare disease patients in the United States and over 5,000 rare disease clinical trials underway. Ending the diagnostic and therapeutic odyssey is finally within our grasp. Without disruptive progress, precision medicine at scale isn’t possible. BeginNGS will help us identify rare disease patients earlier, increase clinical trial enrollment and rapidly progress rare disease treatment.

This pilot includes birthing hospitals throughout the U.S. and abroad.
Blood-spot samples will be collected at the time of birth and sent to the lab where WGS will be performed.
Genomic analysis and interpretation will be performed for ~400 early onset actionable genetic conditions.
When a positive screening result is detected, a confirmatory diagnostic test will be completed before a result is returned to the ordering physician.
Additionally, physicians will be provided with guidance on appropriate medical management, including all available interventions.

ABSTRACT Precision medicine strives for highly individualized treatments for disease under the notion that each individual’s unique genetic makeup and environmental exposures imprints upon them not only a disposition to illness, but also an optimal therapeutic approach. In the realm of rare disorders, genetic predisposition is often the predominant mechanism driving disease presentation. For such, mostly, monogenic disorders, a causal gene to phenotype association is likely. As a result, it becomes important to query the patient’s genome for the presence of pathogenic variations that are likely to cause
J Pers Med. 2022 Nov 18;12(11):1924. doi: 10.3390/jpm12111924. ABSTRACT Rapid genome sequencing in critically ill infants is increasingly identified as a crucial test for providing targeted and informed patient care. We report the outcomes of a pilot study wherein eight critically ill neonates received rapid whole genome sequencing with parental samples in an effort to establish a prompt diagnosis. Our pilot study resulted in a 37.5% diagnostic rate by whole genome sequencing alone and an overall 50% diagnostic rate for the cohort. We describe how the diagnoses led to identification of additional affected relatives and a change in management, the
Cold Spring Harb Mol Case Stud. 2022 Oct 28;8(6):a006169. doi: 10.1101/mcs.a006169. Print 2022 Oct. ABSTRACT We provide the first study of two siblings with a novel autosomal recessive LRP1-related syndrome identified by rapid genome sequencing and overlapping multiple genetic models. The patients presented with respiratory distress, congenital heart defects, hypotonia, dysmorphology, and unique findings, including corneal clouding and ascites. Both siblings had compound heterozygous damaging variants, c.11420G > C (p.Cys3807Ser) and c.12407T > G (p.Val4136Gly) in LRP1, in which segregation analysis helped dismiss additional variants of interest. LRP1 analysis using multiple human/mouse data sets reveals a correlation to patient phenotypes
