NCT ID NCT05448326

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at how to reduce the long and frustrating journey to a diagnosis for people with developmental abnormalities. Researchers will review past cases, collect new blood or skin samples, and use advanced genetic testing. The goal is to understand why some people remain undiagnosed and find ways to change that.
