Gerstmann-Straussler Disease, also known as gerstmann-straussler-scheinker syndrome, is related to progressive myoclonus epilepsy and prion disease, and has symptoms including cerebellar ataxia, muscle rigidity and muscle spasticity. An important gene associated with Gerstmann-Straussler Disease is PRNP (Prion Protein (Kanno Blood Group)), and among its related pathways/superpathways are Alzheimer's disease and miRNA effects and Presenilin-Mediated Signaling. Affiliated tissues include brain and cerebellum, and related phenotypes are cognitive impairment and gait ataxia
