Background: Spinal muscular atrophy (SMA) is a disorder caused by homozygous loss of function the SMN1 gene. This gene produces survival motor neuron (SMN) protein, which important in homeostasis. The SMN2 has homology with SMN1, but only expresses 10% functional full-length SMN protein. treatment available Brazilian public health system Nusinersen, an antisense oligonucleotide that increases p...

AIM Presentation of a prenatally diagnosed case of Werdnig-Hoffmann disease, the most severe type of spinal muscular atrophy. METHODS DNA obtained from cultivated amniocytes was analyzed for deletions in the survival motor neuron gene and neuronal apoptosis inhibitory protein gene. RESULTS The fetus was diagnosed as an affected homozygote for deletions in exon 7 and exon 8 of the survival m...

BACKGROUND Spinal muscular atrophy is an autosomal recessive disorder characterized by degeneration of anterior horn cells in the spinal cord leading to progressive muscular weakness and atrophy. The spinal muscular atrophy candidate interval genes including survival motor neuron, the responsible gene in spinal muscular atrophy phenotype expression, neuronal apoptosis inhibitory protein, and P4...

Spinal muscular atrophy (SMA) is attributed to mutations in the SMN1 gene, leading to loss of spinal cord motor neurons. The neurotropic Sindbis virus vector system was used to investigate a role for the survival motor neuron (SMN) protein in regulating neuronal apoptosis. Here we show that SMN protects primary neurons and differentiated neuron-like stem cells, but not cultured cell lines from ...
