Autosomal recessive spastic paraplegia type 71

Autosomal recessive spastic paraplegia type 71 is a rare, genetic, pure hereditary spastic paraplegia disorder characterized by infancy onset of crural spastic paraperesis with scissors gait, extensor plantar response, and increased tendon reflexes. Neuroimaging reveals a thin corpus callosum and electromyography and nerve conduction velocity studies are normal.
