erlin2 mutations in two iranian families with hereditary spastic paraplegia
spastic paraplegia 18 is an autosomal recessive disorder characterized by motor dysfunction, joint contracture and mental retardation. we describe two families as three cases. case 1 is a 35-year-old woman with and spasticity and mild weakness in lower limbs. case 2 and 3 are a sister and brother aged six and two respectively. the older sister suffered from lower limb spasticity, equinovarus an...
متن کاملHereditary 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,...
متن کاملA recurrent mutation in KCNA2 as a novel cause of hereditary spastic paraplegia and ataxia
The hereditary spastic paraplegias (HSPs) are heterogeneous neurodegenerative disorders with over 50 known causative genes. We identified a recurrent mutation in KCNA2 (c.881G>A, p.R294H), encoding the voltage-gated K(+) -channel, KV 1.2, in two unrelated families with HSP, intellectual disability (ID), and ataxia. Follow-up analysis of > 2,000 patients with various neurological phenotypes iden...
متن کاملStrumpellin and Spartin, Hereditary Spastic Paraplegia Proteins, are Binding Partners
Hereditary spastic paraplegia (HSP) is one of the most heterogeneous neurodegenerative diseases with more than 50 identified genes causing a relatively stereotypical phenotypic presentation. Recent studies of HSP pathogenesis have suggested the existence of shared biochemical pathways that are crucial for axonal maintenance and degeneration. We explored possible interactions of several proteins...
