A new locus for autosomal recessive complicated hereditary spastic paraplegia (SPG26) maps to chromosome 12p11.1-12q14.
T he term hereditary spastic paraplegia (HSP) is used to describe a group of clinically and genetically heterogeneous disorders in which the defining clinical feature is progressive spasticity and weakness of the lower limbs. The phenotype is traditionally classified as ‘‘pure’’ when symptoms and signs are generally confined to those of a progressive spastic paraparesis, or ‘‘complicated’’ when...
متن کاملHereditary spastic paraplegia with thin corpus callosum: reduction of the SPG11 interval and evidence for further genetic heterogeneity.
BACKGROUND Hereditary spastic paraplegia (HSP) with thin corpus callosum (TCC) is an autosomal recessive form of complicated HSP mainly characterized by slowly progressive spastic paraparesis and mental deterioration beginning in the second decade of life. The locus for HSP-TCC, designated SPG11, was mapped to chromosome 15q13-15 in some of the affected families from Japan, Europe, and North Am...

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,...

objective hereditary spastic paraplegia (hsp) is a degenerative disease of genetic origin affecting the corticospinal tracts in the spinal cord. there are three forms of inheritance: autosomal dominant hsp, autosomal rececive hsp and x-linked hsp. this disease is characterized by progressive spasticity of leg muscles with varying degrees of stiffness and weakness of other muscle groups. in this...
