The hereditary spastic paraplegias (HSPs) are inherited neurologic disorders in which the primary symptom is insidiously progressive difficulty walking due to lower extremity weakness and spasticity. There have been great strides in our knowledge of this group of disabling disorders; 20 HSP loci and 9 HSP genes have been discovered. Insights into the molecular causes of HSPs are beginning to emerge. This review summarizes these advances in HSPs' genetics.
遗传性痉挛性截瘫（HSPs）是一类遗传性神经系统疾病，其主要症状是由于下肢无力和痉挛导致行走困难逐渐加重。我们对这组致残性疾病的认识取得了巨大进展；已经发现了20个HSP基因座和9个HSP基因。对HSPs分子病因的认识也开始显现。本综述总结了HSPs遗传学方面的这些进展。
