antenatal and newborn screening programme

SMA

Spinal muscular atrophy (SMA) is a genetic disease. It causes muscle weakness and a progressive loss of movement. There is no cure but therapy and support are available to help manage the condition.

UK NSC screening recommendation Based on the last UK NSC review of this condition that occurred in October 2018.

Screening is not currently recommended for this condition.

Screening for SMA is not recommended by the UK NSC. This is because:

  • there is not evidence to show how effective a screening programme would be
  • the best way to support people who receive positive results is not known
  • there is no evidence for effective treatments for people who do not show symptoms of SMA
  • the long term effects of a new treatment called nusinersen which can improve symptoms in children with SMA are unknown
  • there is no evidence on the effectiveness of nusinersen in children without symptoms
  • the evidence on how well the test for SMA performs is limited
  • there is not enough information about the total number of people affected by SMA
