New treatments in spinal muscular atrophy.

Abstract excerpt

Spinal muscular atrophy (SMA) is a severe neurodegenerative condition due to recessive mutations in the SMN1 gene resulting in insufficiency of survival motor neuron (SMN) protein. Lack of SMN protein results in irreversible degeneration of lower motor neurons and consequential muscle atrophy and weakness. SMN2, a SMN1 homologue, produces low levels of functional SMN protein with the potential to partially...
