BACKGROUND Hereditary spastic paraplegia (HSP) with thin corpus callosum (CC) is a rare neurodegenerative disorder classified as a complicated form of spastic paraplegia. Some patients with HSP with thin CC have previously been described in Japanese families, and the genetic locus was linked to chromosome 15q13-15. OBJECTIVE Our objective was to further clinically and genetically characterize...
OBJECTIVE To translate and validate the Spastic Paraplegia Rating Scale (SPRS) into Brazilian-Portuguese. METHOD Two experienced and English-fluent neurologists translated SPRS into Portuguese, creating SPRS-BR. We then assessed inter and intra-rater reliability of this version using coefficients of correlation and variability in a cohort of 30 patients. RESULTS Mean age of patients and dis...
Mutations in TFG gene have been demonstrated in hereditary motor and sensory neuropathy with proximal dominant involvement (HMSN-P) and hereditary spastic paraplegia (HSP). A broad spectrum of TFG pathology is suspected in motor neuron diseases including amyotrophic lateral sclerosis (ALS). We performed mutation screening of TFG gene in ALS cases and evaluated the biological functions of mutant...
Troyer syndrome is a hereditary spastic paraplegia caused by human spartin (SPG20) gene mutations. We have generated a Drosophila disease model showing that Spartin functions presynaptically with endocytic adaptor Eps15 to regulate synaptic growth and function. Spartin inhibits bone morphogenetic protein (BMP) signaling by promoting endocytic degradation of BMP receptor wishful thinking (Wit). ...
CONTENT Strumpell-Lorrain disease - or familial spastic paraplegia (FSP) - is a rare hereditary neurological disorder, mainly characterized by variable degrees of stiffness and weakening of the muscles, with cognitive impairment, deafness, and ataxia in the more severe cases. We describe two female siblings with FSP programmed for cholecystectomy and subtotal colectomy, respectively, and also h...
Axons contain a smooth tubular endoplasmic reticulum (ER) network that is thought to be continuous with ER throughout the neuron; the mechanisms that form this axonal network are unknown. Mutations affecting reticulon or REEP proteins, with intramembrane hairpin domains that model ER membranes, cause an axon degenerative disease, hereditary spastic paraplegia (HSP). We show that Drosophila axon...
