Cutting-Edge DNA sequencing could end diagnostic nightmares for brain disorders

NCT ID NCT07665554

First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This study will test two advanced DNA sequencing methods—long-read sequencing and optical genome mapping—to find hidden genetic causes of neurogenetic diseases. Researchers will analyze skin biopsy samples from 304 people aged 6 to 60 who have or may have these conditions. The goal is to see if these new techniques can diagnose diseases that standard tests miss, potentially ending long diagnostic journeys for families.

What this could mean

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

Active substance
Skin biopsy (procedure)
What this could lead to
If successful, this could lead to faster and more accurate genetic diagnoses for people with neurogenetic diseases, ending long diagnostic journeys.
What could go wrong
This is an early-stage study that only tests the technology's accuracy; it may not find new causes or directly benefit participants. The procedure is minimally invasive but carries small risks like infection or scarring.
