Objective: To examine the gene mutation associated with clinical phenotype from a Chinese kindred with autosomal dominant hereditary spastic paraplegia (ADHSP). Method: To perform linkage analysis and mutation detection. For two affected individual of the family, clinical analysis, electrophysiological examination, and MRI of brain and spinal cord were also performed. Result: A novel splice-site mutation (REEP1 c417+1g>a) was identified. Central motor conduction time to the first metatarsal interosseus and anterior tibial muscles were clearly prolonged. Thoracic cord atrophy was found from T1 to T10. Conclusion: Our study supports that mutations in REEP1 cause ADHSP and demonstrates genetic heterogeneity in ADHSP. Synapse 63:201-205, 2009.
