Children's Mercy Introduces TaGSCAN, Making Genetic Testing an Affordable Part of Pediatric Care
Called TaGSCAN (Targeted Gene Sequencing and Custom Analysis), the test screens for more than 750 diseases that are the result of a single-gene defect. These diseases include muscular dystrophy, cystic fibrosis, polycystic kidney disease (PKD) and hundreds of diseases that have either been challenging to diagnose or for which no test has been available.
TaGSCAN was developed by the Children's Mercy Center for Pediatric Genomic Medicine. It uses next-generation gene sequencing technology and proprietary software which allows a symptom-based analysis to diagnose genetic diseases. The test is highly sensitive and is performed on DNA extracted from a patient's blood sample.
"We are proud to offer this robust genetic test to children and families who, in many cases, have spent years seeking answers," said Stephen Kingsmore, MB ChB, DSc, FRCPath, Director of the Center for Pediatric Genomic Medicine at Children's Mercy. "With TaGSCAN, thousands of children will be able to receive faster diagnoses that enable better decision-making and prevent patients from being subjected to unnecessary treatments."
TaGSCAN is available to patients who have symptoms suggestive of a hereditary disease or for whom a diagnosis has been difficult to make. Any physician may order TaGSCAN, with results delivered in six to eight weeks. The test, which costs less than $3,200, is currently available to Children's Mercy patients and to referring physicians through the Center for Pediatric Genomic Medicine at Children's Mercy. Like all molecular genetic testing, insurance coverage varies by provider. In the near future, Children's Mercy plans to make the test available to hospitals and medical organizations around the nation.
American Society of Human Genetics (ASHG) 63rd Annual Meeting
Proving the utility of this technology, a new study presented at the American Society of Human Genetics (ASHG) 63rd Annual Meeting, showed that the test can effectively find the cause of previously undiagnosed neurodevelopmental disorders in pediatric patients.
The platform presentation, "Utility of a Strategic Next Generation Sequencing Approach to Genomic Diagnosis of Patients with Neurodevelopmental Disorders," included results from a study of 107 patients with neurodevelopmental disorders, 40 of whom received new diagnoses, and 10 cases where the diagnosis was directly attributed to the initiation of new treatments, discontinuation of unnecessary medications, or the avoidance of invasive procedures.
"Our findings include real-world examples of how this new technology has impacted patient care," said lead investigator Sarah Soden, MD, Developmental and Behavioral Medicine. "By identifying the cause of previously undiagnosed diseases, we are giving families the answers they have been searching for - answers that will hopefully improve their children's lives."
The data were presented Oct. 25 at ASHG in Boston. Dr. Kingsmore will discuss TaGSCAN and answer questions about pediatric genomics from medical professionals, media and the public via Twitter at 1 p.m. Central (2 p.m. Eastern) on Oct. 31 through the @ChildrensMercy account. Join the conversation by including #genomechat and @ChildrensMercy in tweets, and follow along at www.childrensmercy.org/TaGSCAN.

About The Center for Pediatric Genomic Medicine at Children's Mercy Hospital
The first of its kind in a pediatric setting, The Center for Pediatric Genomic Medicine combines genome, computational and analytical capabilities to bring new diagnostic and treatment options to children with genetic diseases. As a leading researcher in pediatric genomic medicine, Stephen Kingsmore, M.B. Ch.B., D.Sc., FRCPath, was named to Medscape's Best Physicians list and his team's STAT-Seq test was one of TIME magazine's Top 10 Medical Breakthroughs of 2012.
