Hereditary spastic paraplegia associated with thin corpus callosum

Autosomal recessive hereditary spastic paraplegia (AR-HSP) associated with thin corpus callosum was recently described in Japan, and most families were linked to chromosome 15 q13-15. We report two patients from two different Brazilian families with progressive gait disturbance starting at the second decade of life, spastic paraparesis, and mental deterioration. One patient presented cerebellar ataxia. Magnetic resonance imaging (MRI) of the head of both patients showed a thin corpus callosum. AR-HSP with a thin corpus callosum is a rare disorder, mainly described in Japanese patients. We found only 4 Caucasian families with AR-HSP with thin corpus callosum described in the literature. Further studies including additional Caucasian families of AR-HSP with thin corpus callosum are required to delineate the genetic profile of this syndrome in occidental countries.     

Hereditary spastic paraplegia with hypoplastic corpus callosum in a Turkish family

Hereditary spastic paraplegia is composed of a heterogeneous group of neurodegenerative disorders and is classified as pure or complicated due to its clinical variability. Autosomal recessive hereditary spastic paraplegia with hypoplastic corpus callosum is a rare form of complicated hereditary spastic paraplegia. In complicated hereditary spastic paraplegia, autosomal dominant, autosomal recessive, and X-linked modes of inheritance have been noted. The diagnostic criteria of autosomal recessive hereditary spastic paraplegia with hypoplastic corpus callosum are inheritance consistent with autosomal recessive trait, slowly progressive spastic paraparesis and mental detoriation, hypoplasia of corpus callosum revealed by brain computerized tomography or magnetic resonance imaging, and exclusion of other disorders by magnetic resonance imaging of the spine and brain as well as other laboratory tests. In this report, the authors present the case of 3 affected siblings in a family from Turkey, whereas 1 child and the con-sanguineous parents were healthy. To the authors' knowledge, it is the first reported case of autosomal recessive hereditary spastic paraplegia with hypoplastic corpus callosum from Turkey.     

Complicated hereditary spastic paraplegia with thin corpus callosum (HSP-TCC) and childhood onset

The hereditary spastic paraplegias (HSPs) are a group of rare disorders with the predominant clinical feature of progressive spastic paraplegia. They are subdivided into pure and complicated forms according to whether the disorder is associated with other neurological abnormalities. We report on two unrelated female Caucasian patients with complicated HSP, aged 16 and 24 years, who showed progressive gait disturbance with spasticity and ataxia as well as cognitive impairment. Onset of symptoms was at age 3 and 10 years, respectively. MRI revealed mild diffuse non-progressive T (2)-signal alterations of cerebral white matter and thinning of the body and genu of the corpus callosum. Some similarity of clinical symptoms and MRI patterns with the phenotype of Mast syndrome prompted a mutation analysis of the SPG21 gene, encoding maspardin, which revealed a wild-type sequence in both patients. Clinical and neuroradiological features in our patients are diagnostic for complicated autosomal recessive hereditary spastic paraplegia with thin corpus callosum (HSP-TCC, SPG11). This disorder, characterized by a typical MRI pattern and a progressive spastic paraplegia that may be associated with dementia and ataxia, may have an onset in early childhood and probably is one of the more common forms of complicated HSP.     

Levodopa-responsive parkinsonism in hereditary spastic paraplegia with thin corpus callosum

Hereditary spastic paraplegia with thin corpus callosum is a rare degenerative disease, which is characterized by a progressive weakness of the lower limbs with a hypoplastic corpus callosum, and is often associated with other symptoms such as mental impairment, amyotrophy, sensory disturbances, dysuria, nystagmus and cataract. We describe two siblings (brother and sister) who showed a thin corpus callosum on MRI, one of whom showed the pure form of progressive spastic paraplegia, while the other showed predominant levodopa-responsive parkinsonism. The present cases are illustrative of a phenotypic heterogeneity in the same family of spastic paraplegia with a thin corpus callosum, despite the identical neuroimaging findings, and also presented another form of autosomal recessive juvenile levodopa-responsive parkinsonism.     

Hereditary spastic paraplegia with thin corpus callosum and cataract: a clinical description of two siblings

We report two siblings with autosomal recessive hereditary spastic paraplegia and thin corpus callosum. These patients had a similar history of progressive spastic gait, followed by mental impairment in the second decade. In addition to rigospasticity, ataxia, and foot deformity, both patients had congenital cataract on ophthalmologic examination. The association of cataract and thin corpus callosum suggests a distinct genetic disorder involving these structures in complicated spastic paraplegia.
