Boston Children’s Hospital accelerates genomic sequencing to expand existing genomic database

Boston Children’s Hospital has embarked on a strategic initiative to expand its research genomics gateway, with plans to sequence the DNA of 3,000 patients with epilepsy or inflammatory bowel disease and their family members.

The program, announced today by Chief Scientific Officer David A. Williams, MD, includes a streamlined process for consenting patients and rapidly linking their genetic data with clinical data from their electronic health records. Although the initiative is aimed at scientific discovery, the sequencing will be performed under clinical-grade (CLIA) conditions, so results will also inform patients’ diagnoses and treatments.

“We believe the combination of disease expertise and large, well characterized patient populations provides Boston Children’s with a unique opportunity to enhance our understanding of disease processes while providing patients with enhanced diagnostics,” says Williams. “In some cases, we may also identify new targets for the development of novel therapies.”

Patients with epilepsy or inflammatory bowel disease of likely genetic origin, undiagnosed after initial clinical genetic testing, will have access to enroll in the genomic sequencing pilot study.

The endeavor is being advanced by expanded vendor relationships with GeneDx (Gaithersburg, MD) and Genuity Science, formerly known as WuXi NextCODE, (Reykjavik, Iceland, Dublin, Ireland and Cambridge, MA). GeneDx is providing DNA sequencing services and clinical confirmation of genetic diagnoses, while WuXi NextCODE’s integrated diagnostics and research database platform is enabling Boston Children’s researchers to more easily interpret genetic variants, compare them with public genomic databases and quickly cross-reference relevant reports in the medical literature.

Seizure expert Ann Poduri, MD, MPH, inflammatory bowel disease expert Scott Snapper, MD, PhD, and their labs will provide disease-specific genetic expertise and interpretation. Both already use DNA sequencing as part of their practice and care for large numbers of patients with these diseases.

“This project will enable us to tap the power of genomics, our disease cohorts and our outstanding faculty expertise in these diseases in a very focused but also broader fashion,” says Kevin B. Churchwell, MD, Executive VP of Health Affairs and Chief Operating Officer at Boston Children’s. “We will not only identify new targets for drug and biological therapy development but also will be able to provide families with answers more quickly while offering the best possible care.”

Building a genomics knowledge base

For data analysis, the initiative will use BCH Connect, the Boston Children’s genomics gateway, first deployed at Boston Children’s in 2016 to integrate and harmonize genomic data for 130 researchers across the hospital. BCH Connect leverages Genuity Science’s proprietary database technology originally developed at deCODE Genetics in Iceland for the analysis, management, storage, sharing and interpretation of genomic data.

Within BCH Connect, Boston Children’s has already compiled a database of DNA sequences from more than 4,000 people whose diseases are being studied by researchers throughout the hospital.

“By accelerating genomic sequencing, analysis and the clinical confirmation of genetic diagnoses, this initiative will help us bring the bench closer to the bedside,” says Sandra Fenwick, President and Chief Executive Officer of Boston Children’s. “This project leverages our outstanding disease expertise, patient populations and world-leading science to advance understanding of rare diseases.” Original article here.
