Hidden SMA carriers could soon be found with new DNA reading technique

NCT ID NCT07332702

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

Summary

This study tests a new way to read DNA that may find hidden carriers of spinal muscular atrophy (SMA). Some people carry two copies of the SMN1 gene side by side, making them carriers that standard tests miss. Researchers will take blood samples from 27 adults and use long-read DNA analysis to spot these hidden duplications, which could improve genetic counseling for couples planning a family.

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 could lead to more accurate genetic testing for spinal muscular atrophy carriers, helping couples better understand their risk of having a child with SMA.

What could go wrong

This is a small, early-stage study (27 participants) focused on improving detection methods, not a treatment trial. The new technique may not prove reliable enough for widespread clinical use.
