Newborn screening for 5qSMA offers the potential for early, ideally pre-symptomatic, therapeutic intervention. However, limited data exist on the outcomes of individuals with 4 copies of SMN2, and there is no consensus within the SMA treatment community regarding early treatment initiation in this subgroup. To provide evidence-based insights into disease progression, we performed a retrospective analysis of 268 patients with 4 copies of SMN2 from the SMArtCARE registry in Germany, Austria and Switzerland.

Since experience with this technique is sparse and follow-up data are lacking, we assessed feasibility, safety, and tolerability of this approach in eight patients with SMA II/SMA III receiving Nusinersen in a multicenter study.
