Autosomal recessive spastic paraplegia type 70

What it is

Autosomal recessive spastic paraplegia type 70 is a very rare, complex subtype of hereditary spastic paraplegia that presents in infancy with delayed motor development (i.e. crawling, walking) and is characterized by lower limb spasticity, increased deep tendon reflexes, extensor plantar responses, impaired vibratory sensation at ankles, amyotrophy and borderline intellectual disability. Additional signs may include gait disturbances, Achilles tendon contractures, scoliosis and cerebellar abnormalities.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
