UK study tests newborn screening for rare muscle disease
NCT ID NCT05481164
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at whether it is practical and acceptable to screen all newborns for spinal muscular atrophy (SMA), a rare genetic disease that causes muscle weakness and can be fatal if not treated early. Over 33,000 babies were screened using a simple blood spot test. The goal was to see how many parents agreed to screening and how reliable the test was, with the hope that early detection could lead to better outcomes.
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 pave the way for nationwide newborn screening for SMA, allowing early diagnosis and treatment before symptoms appear.
- What could go wrong
- This is a feasibility study, not a treatment trial. It only measures uptake and accuracy of screening, not long-term health outcomes. Results may not apply outside the UK.

Inclusion Criteria: * Whose mother is undergoing antenatal care at one of the four Hospital Trusts in the Thames Valley region, whose blood spot will be screened at the NHS Oxford Regenial Genetics Laboratory * Whose mother is able to understand the participant information sheet and is willing to provide her informed consent. * Whose mother is in the second or third trimester of pregnancy (≥18 weeks' gestation), or up to 28 days postnatal (the latter is consistent with the World Health Organisation's definition of a newborn infant or neonate) Exclusion Criteria: * Whose mother is unable to understand written or verbal English which would preclude them from understanding the study
