Sažetak
Spinal muscular atrophy is an autosomal recessive disorder characterized by lower alpha motor neuron degeneration. In most cases,
the disease results from homozygous deletions involving exon 7 of the “survival of motor neuron” (SMN) gene at locus 5q13. The
SMN2 gene is a copy of the SMN1 gene, which generates approximately 10%-15% of the correctly spliced transcript because the gene
contains a single silent nucleotide transition in exon 7, leading to frequent skipping of this exon during RNA splicing. The mechanism
is known as alternative splicing. Increase in the SMN levels has a marked impact in experimental models. This simple and practical
method of transferring genes may have a potential for use in the treatment of motoneuron disease in children and adults.
