[…] spastic paraplegia type 4 Disease definition A rare form of hereditary spastic paraplegia with high intrafamilial clinical variability, characterized in most cases as a pure phenotype with an adult onset (mainly the 3rd to 5th decade of life, but that can present [orpha.net]
Some genotypes tended to present earlier than others, and simplex cases tended to present later than those with clear inheritance patterns, but all types had a wide range of onset age. [news-medical.net]
HSP can be classified as pure or uncomplicated if no additional findings are present (2). Age of onset of HSP can range from early childhood to late adulthood. [dnatesting.uchicago.edu]
Results: Patients differ in several categories depending on the type of mutation present. [jnnp.bmj.com]

Although the disorder is typically referred to as hereditary spastic paraplegia the degree of weakness is variable and ranges from no weakness (full strength) to marked weakness (paraplegia). [rarediseases.org]

Hereditary Spastic Paraplegia (HSP) is a group of rare, inherited neurological disorders. Their primary symptoms are progressive spasticity and weakness of the leg and hip muscles. [sp-foundationorg.presencehost.net]
Many symptoms that are common in people with HSP are not directly caused by HSP but are instead caused indirectly by muscle spasticity, weakness, or hyperactive reflexes. Spasticity Spasticity is an increase in muscle tone with resulting stiffness. [emedicine.medscape.com]
Spasticity primarily affects muscles of leg extension (quadriceps), knee flexion (hamstrings), hip adduction (bringing the knees together, thigh adductor muscles), and muscles that extend the feet (gastrocnemius-soleus [Achilles tendon]). [rarediseases.org]
SPG4 is characterized by slowly progressive muscle weakness and spasticity (stiff or rigid muscles) in the lower half of the body. In rare cases, individuals may have a more complex form with seizures, ataxia, and dementia. [rarediseases.info.nih.gov]

Determining the molecular basis of disease using genetic testing can be useful in predicting prognosis and disease course, and can aid in identification of at-risk family members. [dnatesting.uchicago.edu]
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]
Etiology
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]
Background : Mutations in SPG4/ SPAST represent the most frequent molecular etiology in an autosomal dominant form of Hereditary Spastic Paraplegia (HSP). [mdsabstracts.org]
