Genetic circuitry of Survival motor neuron, the gene underlying spinal muscular atrophy.
The clinical severity of the neurodegenerative disorder spinal muscular atrophy (SMA) is dependent on the levels of functional Survival Motor Neuron (SMN) protein. Consequently, current strategies for developing treatments for SMA generally focus on augmenting SMN levels. To identify additional potential therapeutic avenues and achieve a greater understanding of SMN, we applied in vivo, in vitr...
متن کاملThe survival motor neuron protein in spinal muscular atrophy.
The 38 kDa survival motor neuron (SMN) protein is encoded by two ubiquitously expressed genes: telomeric SMN (SMN(T)) and centromeric SMN (SMN(C)). Mutations in SMN(T), but not SMN(C), cause proximal spinal muscular atrophy (SMA), an autosomal recessive disorder that results in loss of motor neurons. SMN is found in the cytoplasm and nucleus. The nuclear form is located in structures termed gem...

متن کاملMolecular bases of spinal muscular atrophy: the survival motor neuron gene
Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease characterized by degeneration and loss of motor neurons of the anterior horn of the spinal cord. The clinical manifestations include proximal symmetric weakness and progressive muscle atrophy. The identification of the SMN1 gene as determinant of SMA has opened alternative ways of studying the disease. Absence of SMN1...
متن کاملDeletions in the survival motor neuron gene in Iranian patients with spinal muscular atrophy.
INTRODUCTION Spinal muscular atrophy (SMA) is a common neuromuscular disorder with progressive paralysis caused by the loss of alpha-motor neurons in the spinal cord. The survival motor neuron (SMN) protein is encoded by 2 genes, SMN1 and SMN2. The most frequent mutation is the biallelic deletion of exon 7 of the SMN1 gene. In SMA, SMN2 cannot compensate for the loss of SMN1, due to the exclusi...
