Study Description

Multi-center, prospective observational cohort study of individuals with congenital heart defects (CHD). Phenotypic data and source DNA derived from 10,000 probands, parents, and families of interest are being collected to investigate relationships between genetic factors and phenotypic and clinical outcomes in patients with CHD.

Molecular data of the PCGC cohort study are available through two substudies:

  • phs000571 The Pediatric Cardiac Genetics Consortium (PCGC)
  • phs001138 The Gabriella Miller Kids First Pediatric Research Program - PCGC
    • Study Weblink: From Bench to Bassinet: CHD Genes
    • Study Types: Parent-Offspring Trios, Cohort
    • Number of study subjects that have individual level data available through Authorized Access: 9463
