Can a photo help diagnose a rare brain disorder?

NCT ID NCT05600946

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at facial features of males aged 2 to 40 with creatine transporter deficiency (CTD), a genetic disorder that causes intellectual disability, seizures, and behavioral issues. Researchers will examine photos of participants to see if they share common facial traits that could help diagnose CTD. No treatments are being tested; this is purely an observational study to improve recognition of the condition.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If shared facial features are found, this could help doctors diagnose creatine transporter deficiency more easily and earlier.
What could go wrong
This is a very small observational study (19 people) looking only at appearance. It does not test any treatment, and findings may not apply to everyone with CTD.
