Summary

This study looked at nearly 1,000 children who had both a tumor and a developmental problem (like a birth defect or learning delay) before age 18. The goal was to find new genetic syndromes that make kids more likely to get cancer. Researchers collected information from across France over three years to build a database for future research.
