Novel mutations expand the clinical spectrum of <i>DYNC1H1</i> -associated spinal muscular atrophy

Abstract

Our report expands the clinical spectrum of DYNC1H1-related SMA-LED to include generalized arthrogryposis. In addition, we report that the neurogenic peripheral pathology and the CNS neuronal migration defects are often associated, reinforcing the importance of DYNC1H1 in both central and peripheral neuronal functions.
