A novel splicing mutation (c.870+3A>G) in SPG4 in a Korean family with hereditary spastic paraplegia.
Hereditary spastic paraplegia (HSP) is a group of genetically heterogenous neurodegenerative disorders characterized by progressive spasticity and weakness of both lower extremities. Herein, we report a novel splicing mutation (c.870+3A>G) in SPG4 in a Korean family with an autosomal dominant-inherited pure HSP. The mutation is located in intron 5, and results in a deletion of the 188bp-sized exon 5. It is likely that the exon 5 deletion leads to spastin dysfunction and cause the typical symptoms and signs of patients.
