Liver Diseases
Conditions
Brief summary
This study involves the one-time collection of whole blood or saliva samples for the extraction and storage of DNA for use in ongoing and future ChiLDReN studies.
Detailed description
The purpose of this study is to establish a mechanism to collect a genetic biosample from the participants previously enrolled into clinical research under ChiLDReN-supported protocols (PROBE and BASIC). The samples will be linked to the data previously collected on the participant. Samples will be stored in the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) specimen repository and will be used in ongoing and future Network and Ancillary Studies of ChiLDReN to further address the pathophysiology and outcomes of these liver diseases.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Augment a repository of DNA | beginning of study through study completion, an average of 1 year. | The major objective of this protocol is to augment a repository of DNA from participants previously enrolled into clinical research but for whom a DNA biosample was not previously collected. The acquisition and storage of DNA from participants will make available an important resource for future and ongoing studies that may evaluate etiology, pathogenesis, biomarkers, pharmacogenomics, and genetic modifiers of these rare disorders. |
