Abstract

SPAST mutations are the most common cause of autosomal dominant hereditary spastic paraplegias (AD-HSPs), but many spastic paraplegia patients are found to carry no mutations in this gene. In order to assess the contribution of ATL1 and REEP1 in AD-HSP, we performed mutational analysis in 27 SPAST-negative AD-HSP families. We found three novel ATL1 mutations and one REEP1 mutation in five index-patients. In 110 patients with sporadic adult-onset upper motor neuron syndromes, a novel REEP1 mutation was identified in one patient. Apart from a significantly younger age at onset in ATL1 patients and restless legs in some, the clinical phenotype of ATL1 and REEP1 was similar to other pure AD-HSPs.
