A rare genetic neuromuscular disorder with progressive muscle weakness
A string of developments shows England will roll out a national newborn screening programme for spinal muscular atrophy (SMA) via the heel-prick test. The move follows Jesy Nelson’s campaign after her twins were diagnosed with SMA, a condition that can impair muscle movement and breathing. The rollout begins this year and continues into 2027, aiming to provide early diagnosis and treatment opportunities.
