Neonatal screening of premature babies with SMA: the German experience

German clinicians report on their experience in the management of premature newborns diagnosed during newborn screening for SMN1-related proximal spinal muscular atrophy (SMA):

  • there are as yet no international recommendations concerning this sub-population of children (born by definition before 38 weeks’ gestation), whether symptomatic or pre-symptomatic,
  • the files of twelve premature babies screened between 2021 and 2024 and carrying a maximum of 3 copies of the SMN2 gene were used for the study,
  • all were asymptomatic at birth, but the neurological condition of one of them deteriorated at five weeks of age,
  • all benefited from an innovative therapy, most often gene therapy (Zolgensma).

There seems to be a consensus among German practitioners to wait until term before starting to prescribe innovative therapy for these newborns.
