Immune-Mediated Cerebellar Ataxias
Immune-mediated cerebellar ataxias (IMCAs) have diverse etiologies. Paraneoplastic cerebellar degeneration, gluten ataxia, and primary autoimmune... -
Inhibitory effects on L- and N-type calcium channels by a novel CaVβ1 variant identified in a patient with autism spectrum disorder
Voltage-gated calcium channel (VGCC) subunits have been genetically associated with autism spectrum disorders (ASD). The properties of the...
