Proximal spinal muscular atrophy, the most frequent genetic cause of childhood lethality, is caused by homozygous loss or mutation of the SMN1 gene on human chromosome 5, which codes for the survival motor neuron (SMN) protein. SMN plays a role in the assembly of small nuclear ribonucleoproteins and, additionally, in synaptic function. SMN...

Low levels of survival motor neuron (SMN) protein result in spinal muscular atrophy (SMA), a severe genetic disease characterized by motor impairment and premature lethality. Although SMN is a ubiquitous protein, motor neurons are much more vulnerable to low levels of SMN than other cells. To gain insight into the pathogenesis of SMA, we have...
