定义 英文原文(暂无中文)
A rare genetic motor neuron disorder characterized by degeneration of alpha motor neurons in the spinal cord and lower brainstem manifesting between 18 months and 18 years of age and associated with slowly progressive, predominantly proximal muscle weakness. By definition, individuals with proximal spinal muscular atrophy (SMA) type 3 achieve independent ambulation before symptom onset, but ambulation may be lost over the course of the disease.
