Scientists hunt for autism genes in large blood study
NCT ID NCT07311213
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to collect blood samples from 450 people, including individuals with autism spectrum disorder (ASD), their relatives, and healthy controls. Researchers will isolate cells from the blood to study genetic factors and biological processes linked to autism. The goal is to better understand what causes ASD and identify potential targets for future treatments.
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 successful, this research could help identify new genetic causes and biological pathways in autism, potentially pointing toward future therapeutic targets.
- What could go wrong
- This is an early-stage observational study, not a treatment trial. It may not directly lead to new therapies, and findings may take years to translate into clinical practice.
This is an AI summary of the original study and may miss details. Read our disclaimer.

- Phase
-
Not a phased trial
Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.
