The authors have constructed a brief timeline of major clinical research related to hereditary spastic paraplegia (HSP). This timeline summarizes the evolution of HSP research, from the first clinical descriptions by Adolf von Strümpell in 1880 to the present day, with the transformation of these diseases into a rapidly-growing and heterogeneous group of neurogenetic diseases.
Service delivery for people with hereditary spastic paraparesis living in the South West of England.
PURPOSE Hereditary Spastic Paraplegia (HSP) is an inherited nervous system disorder characterized by development of leg weakness, spasms and stiffness. While generally acknowledged that health and social care services can minimise symptoms and improve quality of life, there is a lack of research exploring this from the perspective of people affected by HSP. This qualitative study explored the u...
Axonopathies are a group of clinically diverse disorders characterized by the progressive degeneration of the axons of specific neurons. In hereditary spastic paraplegia (HSP), the axons of cortical motor neurons degenerate and cause a spastic movement disorder. HSP is linked to mutations in several loci known collectively as the spastic paraplegia genes (SPGs). We identified a heterozygous rec...
Background: Strumpel disease and dystonia are inherited disorders with the clinical picture of spastic paraparesis and hyperkinesis respectively. We present a case of a patient born from parents with these diseases who developed neurologic phenomena uncharacteristic for the classical clinical picture of his parents’ disorders. Case report: Patient V., 12, born from his father with generalized d...
The hereditary spastic paraplegias (HSPs) are characterized by spasticity of the leg muscles due to axonal degeneration of corticospinal neurons. Beetz et al. report that the core motor phenotype and axonal pathology of HSPs are recapitulated in mice lacking the HSP-associated gene Reep1. REEP1 is shown to regulate ER structure in motor cortex neurons. The Reep1 knockout mouse should be a very ...
Hereditary spastic paraplegias (HSPs) and ataxias are genetically heterogeneous disorders, with more than 70 genes implicated in each group. A smaller fraction of disorders from both groups manifest both with spastic paresis and ataxia, and recognizing this phenotype helps narrowing down the differential diagnosis. Recently, homozygous and compound heterozygous mutations in CAPN1, which encode ...

Hereditary spastic paraplegia (HSP) is a clinically and genetically heterogeneous group of neurodegenerative disorders that are clinically characterized by progressive spasticity and weakness of the lower limbs. HSP genetic loci are designated SPG1-72 in order of their discovery. In 206 Japanese families with autosomal dominant HSP, SPG4 was the most common form, accounting for 38%, followed by...
Familial spastic paraplegia (FSP) is a heterogeneous group of disorders characterized primarily by progressive lower limb spasticity and weakness. More than 50 disease loci have been described with different modes of inheritance. In this study, we identified a novel missense mutation (c.803G>A, p.R268Q) in the plasma membrane calcium ATPase (PMCA4, or ATP2B4) gene in a Chinese family with autos...
Autosomal recessive cerebellar ataxias and autosomal recessive hereditary spastic paraplegias are clinically and genetically heterogeneous disorders with diverse neurological and non-neurological features. We herein describe a Japanese patient with a slowly progressive form of ataxia and spastic paraplegia. Using whole exome sequencing, we identified a novel homozygous frameshift mutation in SP...
