NCT03070197

Brief Summary

Approximately 400 Congenital heart disease patients will participate in the research study which will include one or more research visits for neurodevelopmental testing, brain MRI, and collection of medical history including previously collected genetic sequencing results. The investigators will explore the association between genetic variants, neurodevelopmental deficits, and brain MRI endophenotype. Analyses will compare groups with and without deleterious de novo mutations.

Outcome Measures

Primary Outcomes (1)

  • Neurodevelopment and behavioral health assessment

    The investigators will compare groups with respect to achievement, IQ, learning disability, specific neuropsychological domains (e.g., memory, attention, executive functions, and visual-spatial/motor integration), adaptive function, behavior, social cognition and symptoms of autism spectrum disorder, and quality of life. The primary study outcome for this aim will be the WRAT4 composite score.

    Day 1

Secondary Outcomes (1)

  • Abnormalities in brain structure and microstructure on MRI

    Day 1

Study Arms (2)

Case/CHD with deleterious mutations

Participants with CHD with damaging de novo mutations or stringently defined deleterious missense mutations) on whole exome sequencing or whole genome sequencing

Control/CHD without deleterious mutations

Participants with CHD without damaging de novo mutations or stringently defined deleterious missense mutations) on whole exome sequencing or whole genome sequencing

Eligibility Criteria

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Congenital heart disease patients aged 8 years and older with prior whole exome sequencing or whole genome sequencing results

You may qualify if:

  • Subjects in whom whole exome sequencing or whole genome sequencing has already been performed, either during the CHD GENES study or, for new centers (Utah or USCF/Stanford), after trios in existing biobanks undergo analysis by whole exome sequencing or whole genome sequencing during the Pediatric Cardiac Genomic Consortium 2 grant cycle
  • Presence of deleterious mutations (damaging de novo mutations or stringently defined deleterious missense mutations) identified on sequencing (Cases) OR absence of such known deleterious mutations (Controls)
  • Males or females, age ≥8 years
  • Diagnosis of congenital heart disease
  • Informed consent obtained

You may not qualify if:

  • History of cardiac transplant
  • A cardiac surgical procedure within 6 months of enrollment
  • Known clinical genetic syndrome, characterized as a monogenic condition with an identified gene associated with abnormalities of the brain structure or function, structural heart disease, and potentially other associated features.
  • Presence of CNV known to be clinically pathogenic. Variants will be classified as pathogenic using accepted types of variant evidence (e.g., population data, computational data, functional data, segregation data) as detailed in the American College of Medical Genetics and Genomics " Standards and Guidelines for the interpretation of sequence variants" (Richards et al, GIM 2015).
  • Overwhelming acquired brain injury, such as a major stroke or severe ischemic injury, that would overshadow the effect of a genetic mutation on outcome in the opinion of the center investigator
  • Lack of reading fluency in English or Spanish
