Protein a potential biomarker of Spinraza treatment responses

In adults with spinal muscular atrophy (SMA), changes in the bloodstream in the levels of a protein called LARGE1 matched treatment responses to Spinraza (nusinersen), a study suggested. Further, LARGE1 levels in the cerebrospinal fluid (CSF) — the liquid that surrounds the brain and spinal cord — were…

AI-based tool to assess muscles, nerves shows promise as biomarker

A newer assessment method known as dEMB, for decomposition electromyography — which uses artificial intelligence (AI) tools to measure nerve and muscle function — strongly correlated with measures of physical function and was able to distinguish people with spinal muscular atrophy (SMA) who were able to walk from those…
