It addresses the genetic cause of SMA by delivering a functional copy of the SMN1 gene into nerve cells. This gene is critical for the function of the nerves that control muscles.
On 7 July 2021 NICE published final guidance for the treatment, making it available to the following groups of children:
- Babies with SMA type 1 if they are 6 months or younger
- Babies with SMA type 1, aged 7 to 12 months if their treatment is agreed by the national multidisciplinary team.
- Pre-symptomatic babies identified as having SMA, up to three copies of the SMN2 gene if their treatment is agreed by the national multidisciplinary team
