Serum neurofilament light chain in pediatric spinal muscular atrophy patients and healthy children

Abstract

Reference sNfL values of our large pediatric control cohort may be applied for future studies. Strong correlations between sNfL and cNfL together with motor function suggest that sNfL may be a suitable biomarker for disease activity in children with 2 SMN2 copies and those with >2 SMN2 copies within their initial stages during early childhood.
