The mode of inheritance may be autosomal dominant, autosomal recessive or X-linked. Among these, autosomal dominant spastic paraplegia （AD-HSP） is the most common type, accounting for 70%-80% of all families. The disease is characterized by lower limb spasticity, hyperreflexia, progressive spastic gait and an extensor plantar response. Pes cavus is one of the commonly reported foot phenotypes.展开更多
