香蕉视频 of Utah Health today announced the launch of a pilot project with a goal of quickly and accurately detecting genetic disorders among newborns in its neonatal intensive care unit (NICU). Clinicians believe that bringing precision medicine to the NICU will transform neonatal care, leading to better diagnosis and treatment of critically ill infants with genetic-related diseases while lowering medical costs and easing the emotional and financial burden on parents and families.
With this project, U of U Hospital will join Primary Children鈥檚 Hospital, also in Salt Lake City, as being part of a small group of hospitals worldwide to offer this type of advanced care.
The multidisciplinary project team, which includes U of U Health pediatric specialists, neonatal physicians, and bioinformatic genomics scientists, will use rapid whole genome sequencing (rWGS) to identify genetic mutations suspected of causing disease.
鈥淩apidly getting information about the genetics involved will help us better diagnose and plan the best treatments for these babies,鈥 says Sabrina Malone Jenkins, M.D., a neonatologist and a U of U Health assistant professor of pediatrics. 鈥淚t allows us to personalize our care in the NICU. Not only does it provide information to the clinician but it also provides an answer to parents of 鈥榳hy is this happening and what can we expect?鈥 This type of testing is the future of clinical care in the NICU.
"Its hard to overstate how transformational this will be for diagnosis and care in the NICU."
Nearly half of all newborns treated in neonatal intensive care units are suspected of having some sort of genetic disorder. But determining what those disorders are鈥攅stimates suggest the existence of up to 7,000 genetically-related diseases鈥攁nd whether they are treatable is problematic because genomic sequencing and analysis isn鈥檛 routinely conducted on these infants. As a result, many children go undiagnosed for years, meaning they are frequently in and out of hospital, a cycle that is agonizing for parents, doctors, and nurses.
On the other hand, genome sequencing offers a tremendous opportunity to circumvent this outcome and increase the potential for treatments that could change the trajectory of a newborn鈥檚 health for a lifetime.
Currently, it can take weeks or even months to get results of genetic testing, a crucial time gap that neonatal physicians say needs to be slashed so they can begin providing the appropriate care as soon as possible. The goal of this project, called NeoSeq, is to cut that turnaround time to 72 hours or less at 香蕉视频 Hospital by having clinicians identify infants in the NICU suspected of having a genetic disease or disorder. They will then ask parents to volunteer their blood, as well as that of their child, to be DNA sequenced using rWGS
鈥(rWGS) potentially reveals hundreds of thousands of changes that occur in DNA,鈥 says Hunter Best, Ph.D., medical director of molecular genetics and genomics at a national reference laboratory and nonprofit enterprise of the 香蕉视频 of Utah that will do the DNA sequencing. 鈥淏y using mom and dad鈥檚 data, you can filter out all of the genetic 鈥榥oise鈥 that鈥檚 not necessarily contributing to the child鈥檚 phenotype (traits). Once you filter out that noise, you can start zeroing in on what is actually contributing to the child鈥檚 condition.鈥
After sequencing, scientists affiliated with U of U Health鈥檚 will use artificial intelligence technologies to analyze genetic variants in the child鈥檚 DNA. The technologies, developed by Mark Yandell, Ph.D., and other scientists at the are capable of pinpointing one or two prime genetic suspects with 95 percent probability in less than four hours.
Once the interpretation of the identified genetic variant(s) is confirmed by ARUP medical directors, a research report will be prepared and doctors can begin planning for treatment based on its findings.
鈥淚t鈥檚 hard to overstate how transformational this will be for diagnosis and care in the NICU,鈥 says Josh Bonkowsky, M.D., Ph.D., a U of U Health professor of pediatric neurology. 鈥淚n five or 10 years, people will look back and realize that this is when it all shifted. This was a time that we stepped over a line in the sand into a new era.鈥
Small investigational studies conducted at U of U Health and ARUP Laboratories have already demonstrated the power of genomic analysis in diagnosing and treating disease in newborns. In addition, the at U of U Health incorporates genomic sequencing into the diagnosis and treatment of older children with undiagnosed diseases. This NICU project represents the next step forward in advancing diagnoses for children.
In all, more than 40 researchers and scientists from U of U Health鈥檚 Department of Pediatrics, Center for Genomic Medicine, Utah Center for Genetic Discovery, and ARUP Laboratories are involved in this project, capitalizing on existing expertise in genetics and genomic medicine. If the pilot is successful, U of U Heath plans to integrate rWGS into the routine clinical care of the most difficult cases in the NICU, joining the first wave of institutions in the nation to do so.
鈥淲hat makes us unique is the collaborative nature of this project,鈥 says Luca Brunelli, M.D., Ph.D., director of the U of U Health Neonatal Genomics Program. 鈥淲e have a broad range of scientific minds involved. We have a tremendous opportunity to discover solutions to important questions and thus benefit so many young lives.鈥
