Spinocerebellar Ataxia 44, also known as sca44, is related to autosomal dominant cerebellar ataxia and aceruloplasminemia. An important gene associated with Spinocerebellar Ataxia 44 is GRM1 (Glutamate Metabotropic Receptor 1), and among its related pathways/superpathways are Signal Transduction and Wnt / Hedgehog / Notch. Affiliated tissues include spinal cord and cerebellum, and related phenotypes are ataxia and dysmetria
