Understanding heart defects in hypoplastic left heart syndrome

Deciphering the intrinsic myocardial and/or endocardial defects of hypoplastic left heart syndrome

['FUNDING_CAREER'] · BOSTON CHILDREN'S HOSPITAL · NIH-11045689

This study is looking into hypoplastic left heart syndrome (HLHS) to find out how certain genes might cause this heart condition, using both patient samples and zebrafish to learn more about how these genes affect heart development, with the hope of discovering better treatments for those affected.

What this research studies

This research investigates hypoplastic left heart syndrome (HLHS), a serious congenital heart condition where the left side of the heart is underdeveloped. The study aims to identify genetic factors contributing to this condition by analyzing genetic variants in patients and using zebrafish models to understand how these defects affect heart development. By exploring the role of specific genes, such as RBFOX2, the research seeks to uncover the mechanisms behind these structural heart defects and their impact on heart function. Patients may benefit from insights that could lead to improved treatments or interventions for HLHS.

Who could benefit from this research

Good fit: Ideal candidates for this research include infants and children diagnosed with hypoplastic left heart syndrome or those with a family history of congenital heart defects.

Not a fit: Patients with heart conditions unrelated to hypoplastic left heart syndrome may not receive any benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and treatment options for patients with hypoplastic left heart syndrome.

How similar studies have performed: Previous studies have shown success in using genetic analysis and animal models to understand congenital heart defects, suggesting that this approach may yield valuable insights.
