Newborn screening for spinal muscular atrophy

Babies born today with spinal muscular atrophy (SMA) don’t have time to wait.  

Without newborn screening, babies are being diagnosed too late to receive effective treatment to prevent permanent muscle damage. Many will never take their first steps freely and will rely on feeding tubes and equipment to help them breathe. 

We must act now. We urgently need every baby in the UK to be screened for SMA shortly after birth. We can’t sit by while delayed diagnosis can steal a baby’s first steps, first milestones and future opportunities.

“Chester needs a ventilator to breathe when he’s asleep or unwell. He has to be fed through an NG [nasogastric] tube because he can’t eat orally. He can’t sit unaided or hold his own head up. The future is so uncertain for Chester, but if SMA was included in the newborn screening heel prick test, he could have received treatment from birth, and he’d have a very different life.”

Kasey, Chester’s mother

What’s happening now

Babies born today with SMA do not have time to wait. Each day a newborn is not tested for SMA means later diagnosis and devastating consequences for their future. We’re committed to ensuring every baby in the UK is screened for SMA.

Northern Ireland

The Northern Ireland government is still failing to act for newborn screening. This isn’t right. But we need your help to change this – we want to meet with your MLAs to talk about what they can do to help.

Wales

There is still no newborn screening for SMA in Wales. We’re meeting the Deputy Health Minister at the end of October. If you’re living in Wales and are affected by SMA, we’d love to hear from you.

England

A programme to screen some newborns started on 1 October 2026. All babies across England will be offered SMA screening by spring 2028 in a phased roll-out. The programme will assess whether to offer newborn screening for SMA permanently.

Scotland

Scotland has already started to test all babies born in Scotland through a pilot programme. This programme is due to end in 2028.

What we’re calling for

  • In England, the government must ensure all babies are offered screening for SMA no later than spring 2028.
  • In Wales and Northern Ireland, the governments must commit to and put in place a plan to screen all babies for SMA.
  • In Scotland, the government must commit to continuing newborn screening once the two-year pilot ends in 2028.

Why we need newborn screening

"It took 23 appointments to diagnose my son with SMA type one"

It took Kasey 23 appointments with nine different doctors to get answers. Find out how their future could have been different if newborn screening was in place for SMA.

"Months without a diagnosis stole so much from Dani. SMA newborn screening could have changed that."

Dani’s dad, Charlie, shares their family’s story to show why every baby in the UK deserves the same chance as those in England and Scotland through newborn screening for SMA.

“If SMA had been included in newborn screening, Ezra’s life could look so different”

Catherine’s son, Ezra, has spinal muscular atrophy (SMA) type 2. She shares the pain of watching him lose strength, the hope treatment has given their family, and why she believes every baby should be screened for SMA at birth.
