What is SMA and why is newborn screening important?

SMA is a devastating muscle-wasting disease. Newborn screening is crucial because effective treatments exist that can prevent irreversible muscle damage if administered at birth.

Has Scotland introduced newborn screening for SMA?

Yes, Scotland has taken a pioneering step by introducing SMA screening for newborns starting in March 2026.

What are the benefits of early SMA diagnosis and treatment?

Early diagnosis and treatment allow infants to achieve developmental milestones, preventing conditions like wheelchair dependency and the need for life-support.

Babies' Lifeline: SMA Screening Urgently Needed

Britain stands at a critical juncture regarding newborn screening for Spinal Muscular Atrophy (SMA), a severe muscle-wasting disease. For years, advocacy groups like SMA UK have pushed for the inclusion of SMA in the newborn heel prick test. Previous rejections were based on a lack of evidence for early treatments.

However, life-changing therapies, including gene therapy, are now available. These treatments are most effective when administered at birth, before irreversible muscle damage occurs. Infants identified and treated presymptomatically can achieve developmental milestones previously thought impossible, such as sitting independently and breathing unaided.
