Summary

This study follows children under 21 who have a genetic condition that raises their risk of developing cancer, along with their relatives. Researchers will collect health information and samples over time to better understand how these cancers develop and how to catch them early. The goal is to improve monitoring and prevention strategies for these high-risk children.
