Ono K. Neuroradiology ; The later are associated with a variety of other neurological and systemic abnormalities, whereas the former essentially present with lower limb weakness and spasticity. Spastic Paraplegia 12, Autosomal Dominant. Figure 1. Childhood onset, complicated: cognitive decline, movement disorders, epilepsy. Mechanistic basis of an epistatic interaction reducing age at onset in hereditary spastic paraplegia. In contrast to routine brain MRI, which is usually normal in uncomplicated HSP, special MRI techniques such as diffusion tensor imaging, reserved primarily for research purposes often show more widespread nerve pathway abnormalities in uncomplicated and complicated HSP. In addition to clearly familial cases, a significant proportion of patients with sporadic spastic paraplegia also have a genetic etiology.
Hereditary spastic paraplegia (HSP) is a group of genetically-determined disorders characterized by progressive spasticity and weakness of lower To date, there are up to 60 genetic types described.

Spastic paraplegia type 3A is one of a group of genetic disorders known as hereditary spastic paraplegias. These disorders are characterized by muscle.
The primary symptom of HSP, walking disturbance due to leg weakness and spasticity also occurs in many other conditions, including non-inherited non-genetic conditions, and as a feature of other inherited neurologic conditions.
Hsp Spastic paraplegia, optic atrophy, and neuropathy: new observations, locus refinement and exclusion of candidate genes. To be clear, the entire spinal cord is not degenerating.

or retrospective studies) and three were class III studies (two RCTs and one.
Dysmorphic features. There is not a perfect correlation between the genetic type of HSP and the pattern of symptoms. GPT2 mutations cause developmental encephalopathy with microcephaly and features of complicated hereditary spastic paraplegia. This impairs nerve transmission from the brain through the spinal cord.
Spastic Paraplegia 24, Autosomal Recessive. Overall, disability in patients with pure HSP tends to progress slower than in patients with spinocerebellar ataxias Spastic Paraplegia 19, Autosomal Dominant.
