Summaries for Spastic Ataxia

About this section
KEGG : 37
Spastic ataxia (SPAX) is a heterogeneous group of progressive neurodegenerative disorders, characterized by lower-limb spasticity and generalized ataxia with dysarthria, impaired ocular movements, and gait disturbance. Mostly, mutations in the mitochondrial factors cause this disease.

MalaCards based summary : Spastic Ataxia, also known as ataxia, spastic, is related to spastic ataxia, charlevoix-saguenay type and spasticity, and has symptoms including ataxia, gait ataxia and dysdiadochokinesis. An important gene associated with Spastic Ataxia is SACS (Sacsin Molecular Chaperone), and among its related pathways/superpathways is Aminoacyl-tRNA biosynthesis. Affiliated tissues include brain, testes and spinal cord.

Disease Ontology : 12 A hereditary ataxia that is characterized by early onset of cerebellar ataxia, pyramidal tract signs and peripheral neuropathy.
