Spastic paraplegia type 15 usually becomes apparent in childhood or adolescence with the development of weak muscle tone (hypotonia), difficultywalking, or intellectual disability.[ghr.nlm.nih.gov]
The primary symptom of HSP is difficultywalking due to weakness and tightness (spasticity) in the legs. Both legs are affected, usually to a relatively similar degree. The term “paraplegia” means severe weakness in both legs including paralysis.[rarediseases.org]

Background: Hereditary spastic paraplegias (HSP) are degenerative diseases of upper motor neurons characterized by a progressive spasticgait disorder which are phenotypically as well as genetically highly heterogeneous.[mdsabstracts.org]
Walking pattern described as “spasticgait” 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 spasticgait disturbance usually progresses over many years.[en.wikipedia.org]

Genetic counseling Hereditary Spastic Paraplegia (HSP) is a group of clinically and genetically heterogeneous disorders characterized by lowerextremityspasticity and weakness.[asperbio.com]
Clinical Features Symptoms depend on the type of HSP inherited Main feature progressive spasticity in the lower limbs, due to pyramidal tract dysfunction In the lowerextremities, spasticity is increased at the hamstrings, quadriceps and ankles[slideshare.net]
Clinically, patients present with slowly progressive distal limb weakness and lowerextremityspasticity. Peripheral sensory neurons may be affected in the later stages of the disease.[reference.md]

Furthermore, among the core symptoms of HSP are also included abnormalgait and difficulty in walking, decreased vibratory sense at the ankles, and paresthesia . [10] Individuals with HSP can experience extreme fatigue associated with central nervous[en.wikipedia.org]

Abstract Although SPG11 is the most common complicated hereditary spastic paraplegia, our knowledge of the long-term prognosis and life expectancy is limited.[nature.com]
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 [ edit ] 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.[en.wikipedia.org]
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]
Accordingly, plasma oxysterols are biomarkers that should be included in the screening of any spastic paraplegia of unknown etiology.[oxfordmedicine.com]
Hereditary Spastic Paraplegia Etiology HSP is a highly genetically heterogeneous group of disorders (4). 70-80% of HSP is inherited in an autosomal dominant manner, and the majority of dominant HSP is classified as uncomplicated or pure HSP (2).[dnatesting.uchicago.edu]
