What this trial studies

This observational study aims to collect whole blood or saliva samples from children with liver diseases and their biological parents who have previously participated in ChiLDReN-supported protocols. The collected genetic biosamples will be linked to existing data from earlier studies and stored in the NIDDK specimen repository. These samples will be utilized in ongoing and future studies to enhance understanding of the pathophysiology and outcomes associated with liver diseases.

Who should consider this trial

Good fit: Ideal candidates include children who have previously participated in ChiLDReN studies and their biological parents who have not yet provided a DNA sample.

Not a fit: Patients who are deceased or who exited prior studies due to eligibility violations will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable genetic insights that improve the understanding and treatment of liver diseases in children.

How similar studies have performed: Other studies involving genetic sample collection for chronic diseases have shown success in advancing research, making this approach promising.
