BACKGROUND Hereditary spastic paraplegia is a group of genetically heterogeneous neurodegenerative disorders characterized by progressive spasticity of the lower limbs. The most common form of hereditary spastic paraplegia is caused by mutations in the spastin gene (SPG4), which encodes spastin, an adenosine triphosphatase associated with various cellular activities protein. OBJECTIVE To inve...
OBJECTIVE To study the frequency and distribution of mutations in SPG3A in a large cohort of patients with hereditary spastic paraplegia. DESIGN We screened a large cohort of 182 families and isolated cases with pure or complex hereditary spastic paraplegia phenotypes, which were negative for mutations in SPG4. RESULTS In 12 probands (6.6%), we identified 12 different SPG3A mutations (11 mi...
BACKGROUND Autosomal recessive hereditary spastic paraplegia (ARHSP) with thin corpus callosum (TCC) is a complicated form of hereditary spastic paraplegia, characterized by progressive spastic paraplegia, weakness of the lower extremities and is usually accompanied by mental retardation. Mutations in the Spastic Paraplegia gene 11 (SPG11) account for a large proportion of ARHSP-TCC cases world...
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...
Hereditary spastic paraplegia (HSP) is a neurodegenerative disease characterized by progressive spasticity in the lower extremities. Mutations in the atlastin GTPase 1 (ATL1) gene cause approximately 10% of autosomal dominantly inherited HSP. For many subjects with an ATL1 mutation, spastic gait begins in early childhood and does not significantly worsen, even over many years; such cases resemb...
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,...
The hereditary spastic paraplegias are a group of heterogeneous disorders characterised by lower limb spasticity. Although most cases represent a ‘pure’ form, variants with additional ‘complicating’ features have been documented [1]. We report a patient with hereditary spastic paraplegia (HSP) having a demyelinating form of polyneuropathy which has not been previously associated with this condi...
BACKGROUND Mutations in the spatacsin gene are associated with spastic paraplegia type 11 (SPG11), which is the most-common cause of autosomal recessive hereditary spastic paraplegia. Although SPG11 has diverse phenotypes, thinning of the corpus callosum is an important feature. CASE REPORT Clinical, genetic, and radiological evaluations were undertaken in a large family from Gujarat in North...
Bektaş G, Yeşil G, Yıldız EP, Aydınlı N, Çalışkan M, Özmen M. Hereditary spastic paraplegia type 35 caused by a novel FA2H mutation. Turk J Pediatr 2017; 59: 329-334. Hereditary spastic paraplegia type 35 (SPG35) is a rare disorder characterized by progressive spasticity. Mutations in the fatty acid 2-hydroxylase (FA2H) gene in different loci are responsible for phenotypic variability. We aimed...
