Project Singular
There are far too many questions surrounding single ventricle heart defects and not enough answers. Researchers and clinicians need a clear, fundamental understanding of what causes and complicates single ventricle to be able to prevent and treat it—and they’re currently operating without a full picture of the disease.
Project Singular is a research study to identify the underlying genetic elements that contribute to the development of the disease and related outcomes.
About the Study
Project Singular will collect saliva samples from 5,000+ single ventricle patients and their immediate families to perform whole-genome sequencing, creating the world’s largest genetic repository of single ventricle patients.
Study Objectives
- Develop a comprehensive genetics dataset to identify and understand the genetic causes of single ventricle heart defects and related sequelae
- Establish standardized protocols for acquisition, transfer, and analysis of genetic samples
- Leverage de-identified genetics and health records to identify new clinical, imaging, and biological markers

Our Data Philosophy
We don’t know where the greatest discoveries will be made — so we aim to be as open as possible and strive for true democratization of data, while protecting our participants’ privacy at all costs. Researcher access to phenotypic and anatomic data will be intentionally inclusive and may range from basic science to single ventricle-specific investigation.
