Нусинерсен

Nusinersen is a prescription medication used to treat adult and paediatric spinal muscular atrophy (SMA) by improving peripheral muscle function.SMA is caused by a mutation in a gene called SMN1, which encodes for a protein important for motor neuron survival (survival motor neuron or SMN). Although a nearly identical gene (SMN2) serves as a backup to SMN1, it produces a shorter, less stable protein that does not fully compensate for the loss of the full-length protein normally produced by the SMN1 gene. In contrast, Nusinersen is an antisense oligonucleotide agent that modifies the pre-messenger RNA splicing of the SMN2 gene, thereby facilitating increased production of full-length SMN proteins^[1-2].
