SMN transcript stability: could modulation of messenger RNA degradation provide a novel therapy for spinal muscular atrophy?

Abstract excerpt

Proximal spinal muscular atrophy is caused by deletion or mutation of the survival motor neuron 1 gene, SMN1. Rentention of a nearly identical copy gene, SMN2, enables survival but is unable to fully compensate for the loss of SMN1. The SMN1 and SMN2 genes differ by a single nucleotide that results in alternative splicing of SMN2 exon 7 due to the disruption of a binding site for an essential splicing factor....
