Dual Masking of Specific Negative Splicing Regulatory Elements Resulted in Maximal Exon 7 Inclusion of SMN2 Gene
9 Dec 2013
Abstract excerpt
Spinal muscular atrophy (SMA) is a fatal autosomal recessive disease caused by survival motor neuron (SMN) protein insufficiency due to SMN1 mutations. Boosting SMN2 expression is a potential therapy for SMA. SMN2 has identical coding sequence as SMN1 except for a silent C-to-T transition at the 6th nucleotide of exon 7, converting a splicing enhancer to a silencer motif. Consequently, most SMN2 transcripts lack...
