Autosomal Recessive Spastic Paraplegia Type 48

SPG48

Most patients presented with spastic paraparesis. Additional features included ataxia, dystonia, intellectual impairment, myoclonus, and parkinsonism. One patient presented with pure sensory and motor neuropathy. [ng.neurology.org]

Autosomal recessive HSP as well as sporadic cases present a significant diagnostic challenge. [mobile.fluidigm.com]

Abstract Objective: To identify the gene mutation responsible for a family presenting spastic paraplegia, cerebellar ataxia and neuropathy with autosomal recessive transmission. [trace.ddbj.nig.ac.jp]

HSP is classified according to the clinical phenotype as either pure or complex, the latter presenting with neurological and systemic impairments in addition to spastic paraparesis. [journals.lww.com]

CASE PRESENTATION: We describe a Chinese family with ARHSP-TCC. Two daughters of this family presented with a spastic gait and cognitive impairment. Brain imaging of the index patient revealed a thin corpus callosum. [hspersunite.org.au]

  • Pallor

    The pathologic hallmarks of the disease include pallor of the corticospinal tract due to loss of motor neurons, presence of ubiquitin-positive inclusions within surviving motor neurons, and deposition of pathologic aggregates. [genecards.org]

    Discs show mild temporal pallor. An EMG/NCS indicated an axonal sensory polyneuropathy. Somatosensory evoked potentials showed an abnormal central response in the right upper limb. [ng.neurology.org]

    There is diffuse myelin pallor of crossed and uncrossed corticospinal tracts. In addition, the gracile fasciculi in the centre of the dorsal columns show prominent myelin pallor. Anterior horn cells are normal in number and morphology. [jnnp.bmj.com]

  • Numbness of the Feet

    He developed a spastic bladder and pain and numbness in both feet. On examination, the patient exhibited prominent lower extremity spasticity with mild distal muscle weakness and mild weakness of the hip flexors. Cognition was intact. [ng.neurology.org]

  • Hypomimia

    As his gait problems progressed, his family noted facial hypomimia and bradykinesia. He developed a spastic bladder and pain and numbness in both feet. [ng.neurology.org]

  • Spastic Gait

    If symptoms begin during the teenage years or later, then spastic gait disturbance usually progresses over many years. [ipfs.io]

    Two daughters of this family presented with a spastic gait and cognitive impairment. Brain imaging of the index patient revealed a thin corpus callosum. [hspersunite.org.au]

  • Bradykinesia

    As his gait problems progressed, his family noted facial hypomimia and bradykinesia. He developed a spastic bladder and pain and numbness in both feet. [ng.neurology.org]

    Only one of five patients with hereditary spastic paraplegia showed clinical indication of extrapyramidal involvement in the form of subtle bradykinesia and slight resting tremor. [intechopen.com]

    Charcots studies between 1868 and 1881 were a landmark in the understanding of Parkinsons disease, among other advances he made the distinction between rigidity, weakness and bradykinesia. [wikivisually.com]

  • Lower Extremity Spasticity

    On examination, the patient exhibited prominent lower extremity spasticity with mild distal muscle weakness and mild weakness of the hip flexors. Cognition was intact. [ng.neurology.org]

  • Neurologic Manifestation

    Kosofsky, Weill-Cornell University Medical Center - Neurologic Manifestations of Medical Disorders-John C. Probasco, Johns Hopkins University [books.google.com]

She developed urinary incontinence, and urological workup disclosed a spastic bladder. No dementia was evident. [ng.neurology.org]

Our findings confirm that this is indeed not an uncommon presentation of this disorder and we suggest that SPG7 gene analysis should be included in the diagnostic workup of autosomal recessive PEO, especially if spasticity is present. [journals.plos.org]

  • White Matter Lesions

    In family I, the white matter lesions were more prominent in older patients ( Fig 1 A ), in contrast to family III, where the white matter lesions were more prominent in the younger patients. [ajnr.org]

    MRI of the brain disclosed white matter lesions affecting the basal ganglia and deep white matter and focal atrophy of the corpus callosum ( figure 1 ), while a full spine MRI was normal. [ng.neurology.org]

    There are occasional reports of mild to moderate atrophy of intracranial structures, particularly the corpus callosum, and also of white matter lesions in the cerebral hemispheres. 15 71 79 80 However, marked atrophy or changes in white matter on MRI [jnnp.bmj.com]

Prognosis Although HSP is a progressive condition, the prognosis for individuals with HSP varies greatly. It primarily affects the legs although there can be some upperbody involvement in some individuals. [ipfs.io]

Disorders, the prognosis of which differs significantly from HSP, such as multiple sclerosis and familial motor neuron disease should also be excluded. The necessity for investigations will vary depending on the individual clinical picture. [jnnp.bmj.com]

Identification of the specific mutation concerned is essential to establishing a prognosis and providing satisfactory treatment and proper genetic counselling. [elsevier.es]

Epidemiology Worldwide, the prevalence of all hereditary spastic paraplegias combined is estimated to be 2 to 6 in 100,000 people. [15] A Norwegian study of more than 2.5 million people published in March 2009 has found an HSP prevalence rate of 7.4/100,000 [ipfs.io]

Epidemiology The prevalence of HSP varies in different studies. Such variation is probably due to a combination of differing diagnostic criteria, variable epidemiological methodology, and geographical factors. [jnnp.bmj.com]
