Spinal muscular atrophy in childhood.
نویسنده
چکیده
Diagnosis and classification of spinal muscular atrophy (SMA) in childhood are based on clinical, electrophysiological, and histological studies. The concept of maturational arrest of motoneurons and their targets (muscle cells in SMA type I) is documented by ultrastructural and immunohistochemical data. The prolongated or markedly delayed process of muscle cell and motoneuron elimination by apoptosis seen in SMA type I is discussed according to the new finding of a gene for a neuronal apoptosis inhibitory protein that is partially deleted in children with spinal muscular atrophy.

Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...

A coarse tremor was noted in 13 children suffering from the childhood form of spinal muscular atrophy. Tremor has not been seen in any other condition producing proximal muscle weakness in childhood, and its presence should therefore suggest the d...
