Presentation
A pendular nystagmus may be present while esophoria or esotropia is present in many patients. Systemic Features: There is a great deal of clinical heterogeneity in this group of ciliary dyskinesias. [disorders.eyes.arizona.edu]
Dysphagia is present and Rombergism and pseudoathetosis are observed. NCVs and nerve biopsy reveal demyelinating and axonal features. Anti-GD1b or GQ1b (consistently present) antibodies, IgM paraproteins and cold agglutinins are present. [neuroweb.us]
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]
The risk of an individual inheriting the abnormal gene depends on the mode of transmission and whether the mutated gene is present on a sex chromosome or an autosome. [encyclopedia.com]

Neurologic
- Spastic Gait
The original description of hereditary spastic paraplegia was made by Strümpell in 1880. He described “a pure spastic movement disorder of the legs” in 2 brothers who developed a spastic gait at the ages of 37 and 56 years. [medlink.com]
Walking pattern described as “spastic gait” occurs in which the following elements are present, each to variable degree in different individuals: a) heel strike is shifted forward (landing on the mid-foot or even further forward on the balls of the feet [rarediseases.org]
If symptoms begin during the teenage years or later, then spastic gait disturbance usually progresses over many years. [ipfs.io]
Diagnosis of SPG is established by the following clinical features 1, 2 : Typical clinical symptoms of spastic gait impairment and neurologic findings of spastic weakness, hyperreflexia, typically associated with bilateral extensor plantar responses A [centogene.com]
Lewy bodies were seen in the substantia nigra. 12 The proband manifested slowly progressive spastic gait since age 18. [demneuropsy.com.br]

Symptoms include hyperreflexia, extensor plantar responses, degeneration of the lateral corticospinal tracts, decreased vibratory sense in the lower limbs, pes cavus and atrophy of the shins. [cags.org.ae]
People with spastic paraplegia type 31 can also experience progressive muscle wasting (amyotrophy) in the lower limbs, exaggerated reflexes (hyperreflexia), a decreased ability to feel vibrations, reduced bladder control, and high-arched feet ( pes cavus [ghr.nlm.nih.gov]

Cranial neuropathies, particularly bilateral facial nerve palsy, transverse myelitis, spastic paraparesis, disturbances in micturition, Babinski sign are also observed during this stage. [neuroweb.us]
Workup
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]
Treatment
Food and Drug Administration has chosen Wave Life Sciences’ planned phase 2/3 study of suvodirsen, its lead experimental therapy for the treatment of Duchenne muscular dystrophy, to break new ground. [globalgenes.org]

Prognosis
Prognosis: predicting symptoms and course of HSP As noted above, there is significant variation in HSP symptoms and their severity. This limits the certainty of making predictions. [rarediseases.org]
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]
As there is a continual increase in WES-generated data on genetic variants, the pool of modifier genes likewise grows and diagnostic inferences will become more accurate, thus providing the grounds for a more precise prognosis. [wjgnet.com]
Prognosis This varies widely, but most often HSP is compatible with a normal life expectancy. The rate of progression varies considerably and is influenced by the mode of inheritance. [encyclopedia.com]
Prognosis Edit Although HSP is a progressive condition and usually starts in the legs and spreads to other muscles, ultimately leading to confinement to bed, the prognosis for individuals with HSP varies greatly. [psychology.wikia.com]
