Any pure hereditary spastic paraplegia in which the cause of the disease is a mutation in the REEP2 gene.
Features include always present findings: Babinski sign and Lower limb hyperreflexia; and very common findings: Spastic gait, Spasticity, and Muscle stiffness (rigidity). 19 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Brain and nerves | 12 | Babinski sign, Lower limb hyperreflexia, Dysarthria |
REEP2 function has not been fully characterized.
Hereditary spastic paraplegia 72 is associated with mutations in the REEP2 gene on chromosome 5.
Genetic testing for REEP2 is available. Testing is considered confirmatory for diagnosis.
