SPG4 HSP

Die SPG4 wird meist als reine HSP klassifiziert, da über die Paraparese hinausgehende komplexe neurologische Symptome selten sind. In Einzelfällen wurden komplexe Phänotypen mit zusätzlicher zerebellärer Ataxie, epileptischen Anfällen, schmalem Corpus callosum und mentaler Retardierung beschrieben Spastic paraplegia 4 (SPG4) is the most common type of hereditary spastic paraplegia (HSP) inherited in an autosomal dominant manner. Disease onset ranges from infancy to older adulthood. SPG4 is characterized by slowly progressive muscle weakness and spasticity (stiff or rigid muscles) in the lower half of the body BACKGROUND AND PURPOSE: SPAST mutations are the most common cause of hereditary spastic paraplegia (SPG4-HSP), which is characterized by progressive lower limb weakness, spasticity and hyperreflexia. There are few studies about non-motor manifestations in this disease and none about autonomic involvement. Therefore, the aim was to determine the frequency and pattern of autonomic complaints in patients with SPG4-HSP, as well as to determine the clinical relevance and the possible factors. Damage in SPG4-HSP extends to the peripheral nervous system. Our results indicate that SPG4-HSP patients have sudomotor dysfunction caused by damaged small post-ganglionic cholinergic fibers. Damage in SPG4-HSP extends to the peripheral nervous system. Autonomic dysfunction in hereditary spastic paraplegia type

  1. Cortical thickness and right hippocampus volume were positively correlated with the MoCA score and subscores.

The mouse model that we used in this study was an essential mammalian model to be tested for a rescue of spastin levels in neurons.

Therefore, studies on animal models with a stronger phenotype at the heterozygous status (such as

SPG4-HSP is a heterogeneous disorder characterized by both interfamilial and intrafamilial variation, especially regarding the severity and the age at onset. In this study, we investigated the origin of the mutation and the factors involved in intra-familial heterogeneity in a family with a SPG4 mutation. We demonstrated that the mutation occurred de novo and show evidence of somatic mosaicism. OBJECTIVE: A family with SPG4-HSP known to have a deletion of exon 17 in the spastin gene (SPG4delEx17) was cognitively assessed over a 7-year period. The index family member died and a postmortem examination was performed. METHODS: Thirteen family members older than 40 years were clinically and cognitively assessed using the Cambridge Cognitive Assessment over a 7-year period. The presence of. SPG4 HSP is characterized by large inter- and intrafamilial variability in age at onset (AAO) and disease severity. The broad spectrum of SPG4 mutations has recently been further extended by the.

The patient presented with a typical pure form of HSP with progressive lower extremity weakness and spasticity, but he also developed lower limb amyotrophy, spinal cord atrophy, and progressive CSF protein elevation, which has not previously been described in SPG4 HSP In SPG4-HSP, there are few previous image-based studies with small cohorts, but none of them employed a multimodal MRI-approach [2,17-19]. In addition, in some of these studies patients with distinct HSP genetic subtypes were combined into a single analysis increasing the possibility of introducing confounding factors as a result of genetic and clinical heterogeneity [ 20 , 21 ] The greatest advance in recent years with HSP was with Dr. Allan McKay-Simm in Australia who hypothasizes that a drug called noscapine will help prevent the progression and hopefully help people with SPG4 HSP. The clinical trial of which should take place this year in Australia. CRISPR is another technology that a lot of people with genetic diseases are hanging their hopes on Noscapine is a good candidate because it is approved in some countries for other indications, it is off-patent, and could be repurposed for SPG3A and SPG4 HSP. GW3965, a liver X receptor (LXR) agonist, rescued three phenotypes (reduced neurite growth, increased growth cone area, axonal swellings) in SPAST HSP neurons, providing a potential drug target for HSP treatment [ 36 ] SPG4-HSP has been defined as a 'pure' HSP, based on the neurological symptoms presented by affected patients, with the lesions being restricted to the corticospinal tract and the posterior column (Hazan et al., 1999; Fonknechten et al., 2000)

Studies on neurons generated from SPG4-HSP patient-derived induced Pluripotent Stem cells, reported spastin reduction asso-ciated with alterations in neurite morphology, swellings and transport deficits (24, 25). Currently, there is no cure for HSP. Im-portantly, in patients' neurons a spastin gene dosage-dependent rescue of the defects has been recently reported by lentiviral spastin. SPG4 HSP is the single most common dominantly inherited HSP, representing approximately 40% of such cases. Hazan and colleagues discovered that mutations in a novel gene designated SPG4 (protein. Some authors report subtle cognitive decline while others report dementia or mental deficiency in SPG4 HSP patients. Most of these studies used a global cognitive efficiency test such as mini-mental state examination (MMSE), Mattis dementia rating scale, short test of mental status (STMS), Cambridge cognitive examination (CAMCOG), and Wechsler adult intelligence scale (WAIS) [ 4 , 5 ]

Spastic Paraplegia, Hereditary Subject Areas on Research. Background: Hereditary Spastic Paraplegia (HSP) is a slowly progressive neurodegenerative disorder with no disease modifying treatment. Potential therapeutic approaches are emerging and large-scale clinical drug trials for patients with HSP are imminent. A sensitive biomarker to measure the drug efficacy in these trials is required. Motor evoked potentials (MEPs) are a potential biomarker for. The present report further extends the spectrum of SPAST mutations and the genotype-phenotype correlation in SPG4 HSP, and highlights the finding of elevated CSF protein levels in some cases.

Using a positional cloning strategy based on the spastic paraplegia-4 (SPG4; 182601) candidate region on chromosome 2p22-p21, Hazan et al. (1999) identified a gene encoding a member of the AAA protein family (see 601681), which they named 'spastin' (SPAST).The deduced spastin protein contains 616 amino acids and has a molecular mass of approximately 67.2 kD Subgroup analysis of SPG4 HSP (10 subjects) revealed significant correlation between TA and AH CMCT with disease duration (r=0.841, p=0.001; r=0.930, p=0.001) but not SPRS scores. Conclusion Lower limb CMCT was absent or prolonged in the majority of subjects. Despite being potentially useful as a diagnostic biomarker for HSP, this study only showed a correlation between lower limb CMCT and. Hereditary spastic paraplegia (HSP) is not a single disease entity; it is a group of clinically and genetically diverse disorders that share a primary feature, which is the causation of progressive and generally severe lower extremity weakness and spasticity.

Hereditary Spastic Paraplegia (HSP), also called Familial Spastic Paraplegias or Strumpell-Lorrain disease, is a form of paraplegia, group of inherited diseases whose main feature is progressive stiffness and contraction in the lower limbs with eventual paralysis, as a result of damage to dysfunction of the nerves. It sometimes also affects the optic nerve and retina of the eye, causes. The sequence analysis of the SPG3A, SPG6, SPG8, SPG10, SPG13, SPG31 and SPG33 genes did not reveal any coding mutations in any of the 30 affected individuals with SP.. There was a large dissimilarity of the age-at-onset between SPG4 and non-SPG4 patients (mean age at onset ±SD: 59.8 (SD 5.1) and 22.1 (SD 3.7), respectively; p<0.0001). Intra-familial phenotypic variations were observed and, in. process to test the effectiveness of a candidate drug for treating SPG4 HSP, associated with mutations in the SPAST gene.

SPG4 HSP patients have a mutation in SPAST, a gene that encodes Spastin, a microtubule severing protein. Patients with SPG4 HSP have 50% of the spastin, 50% of the acetylated atubulin and 150% of the stathmin, a microtubule destabilizing enzyme compared to people without HSP (control). Dr. Mackay- Sim, PhD hypothesizes that SPG4 HSP patients probably compensate for reduced spastin with. The SPG4 HSP patients had clinical features characteristic of uncomplicated HSP. All patients had grossly normal MRI of the brain with the exception of subject 12, who had a remote left occipital lobe stroke; we did not detect any areas with increased signal from the deep white matter on T2-weighted images.
