Summaries for Spastic Ataxia

About this section
KEGG : 36 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 spastic ataxia 1, autosomal dominant, 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 spinal cord, eye and brain, and related phenotypes are behavior/neurological and nervous system

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