Comparison of Clinical Targeted Next Generation Sequencing (NGS) in FFPE with Whole Genome Sequencing (WGS) of Snap Frozen Pediatric Brain Tumors
Email Principal Investigator
About this
Project
DNA sequencing is a process by which scientists identify the base chemicals that make up DNA. The order of these base chemicals act like a computer’s code and serve as instructions for how cells should function. Sequencing the DNA found in tumor samples is important for better understanding cancers and creating treatments. Whole Genome Sequencing (WGS) does this for the entire set of genes and each base present in a tumor cell. Next Generation Targeted Sequencing (NGS) processes target areas in the genome that are known to be actionable and drive tumor mechanisms. Researchers will compare WGS sequencing data and targeted sequencing data to validate the targeting sequencing and potentially develop more precise diagnostics for pediatric brain cancers.
Ask The
Scientists
What are the goals of this project?
The goal of this project is to compare and contrast the genetic results of targeted NGS with WGS for patients who have already had both methods of testing.
What is the impact of this project?
Through comparison of WGS data from CBTN and NGS data, researchers will gain insight into how to diagnose and treat pediatric brain tumors.
Why is the CBTN request important to this project?
Researchers have completed targets NGS on many patients also represented in the Pediatric Brain Tumor Atlas. Access to the PBTA is therefore crucial for the completion of this project.
Specimen Data
The Children's Brain Tumor Network contributed to this project by providing access to the Pediatric Brain Tumor Atlas.
