Neurodevelopmental consequences of Smn depletion in a mouse model of spinal muscular atrophy

Abstract excerpt

Deletions or mutations in survival of motor neuron 1 (SMN1) cause motor neuron loss and spinal muscular atrophy (SMA), a neuromuscular disorder, with the most severe type manifesting in utero. Whether SMA is a disease of defects in neurodevelopment and/or neuromaintenance remains unclear. We performed an analysis of Smn gene and protein expression during murine embryogenesis. Furthermore, we examined...
