Normal Dopaminergic Nigrostriatal Innervation in SPG3A Hereditary Spastic Paraplegia

SPG3A gene polymorphisms in hereditary spastic paraplegia

Objective: This study aimed to analyze the hereditary spastic paraplegia (HSP)/spastic paraplegia 3A (SpG3A) genomic structure as well as the polymorphisms in SPG3G genomic structure by comparing with the normal subjects. Methods: A total of 66 sporadic cases with HSP were collected from April 2014 to September 2016. Genomic DNA extraction was performed, and all coding exons and junction region...

Pharmacologic rescue of axon growth defects in a human iPSC model of hereditary spastic paraplegia SPG3A.

Hereditary spastic paraplegias are a large, diverse group of neurological disorders (SPG1-71) with the unifying feature of prominent lower extremity spasticity, owing to a length-dependent axonopathy of corticospinal motor neurons. The most common early-onset form of pure, autosomal dominant hereditary spastic paraplegia is caused by mutation in the ATL1 gene encoding the atlastin-1 GTPase, whi...

Hereditary spastic paraplegia.

Hereditary spastic paraplegia (HSP) or Strümpell-Lorrain syndrome is a heterogeneous group of inherited disorders, with prevalence ranged from 4.3 to 9.6 cases per 100,000 population. A common feature of these disorders is the slowly progressive and often severe spasticity, noticeably especially in the low limbs. Conventionally, HSP is divided into two clinical groups, uncomplicated (pure spast...

111 families, and Paskind and Stone (1933) also summarized the literature with accounts of another 36 reports from 40 families. Since then about 50 further reports have appeared, covering some 60 families, bringing the total so far to 176 reports of 215 families. Of these the majority have originated in Germany or elsewhere in Europe, but with a substantial number from the Americas. In Britain,...
