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]
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]
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]
