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]
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]
This process is due to mutations in the gene SPAST, located on the shortarm of chromosome 2 (2p24-p21)., Encoding spastin protein.[ivami.com]

The majority of the families where the link has been established are associated with the SPG4 gene location on the shortarm of chromosome 2. The evidence is suggestive that the SPG4 gene regulates production of a protein referred to as, 'spastin.'[disabled-world.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]
