Autosomal dominant spastic paraplegia type 10 (SPG10) is a rare type of hereditary spastic paraplegia that can present as either a pure form of spastic paraplegia with lower limb spasticity, hyperreflexia and extensor plantar responses, presenting in childhood or adolescence, or as a complex phenotype associated with additional manifestations including peripheral neuropathy with upper limb amyotrophy, moderate intellectual disability and parkinsonism. Deafness and retinitis pigmentosa were reported in one case.
Features include always present findings: Babinski sign, Spastic gait, Lower limb muscle weakness, and Lower limb hypertonia; and common findings: Impaired vibration sensation in the lower limbs, Sideways curvature of the spine (scoliosis), Pes cavus, and Urinary urgency and others. 18 total HPO annotations.
Organ System | Phenotype Count | Example Features |

Brain and nerves | 8 | Parkinsonism, Babinski sign, Ataxia |
KIF5A encodes kinesin family member 5A (1,032 aa). Microtubule-dependent motor required for slow axonal transport of neurofilament proteins (NFH, NFM and NFL). Highest expression in Brain Cortex (1,160 TPM) and Brain Frontal Cortex BA9 (1,085 TPM).
Hereditary spastic paraplegia 10 is associated with mutations in the KIF5A gene on chromosome 12.
KIF5A is classified as a druggable target with score 0.0.
Genetic testing for KIF5A is available. Testing is considered confirmatory for diagnosis.
Biomarker and diagnostic research for hereditary spastic paraplegia 10 has been reported in the published literature.
Phenotype severity distribution: 4 always present features, 6 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for hereditary spastic paraplegia 10.
73 publications have been identified in PubMed for hereditary spastic paraplegia 10. Research spans Case Report / Case Series (25%), Basic Science / Preclinical (25%), and Epidemiology / Natural History (21%).
