Genes affected

SLC8A2 (HGNC:11069): (solute carrier family 8 member A2) Predicted to enable calcium:cation antiporter activity involved in regulation of postsynaptic cytosolic calcium ion concentration and calcium:sodium antiporter activity. Predicted to be involved in several processes, including inorganic cation transmembrane transport; learning or memory; and regulation of short-term neuronal synaptic plasticity. Predicted to act upstream of or within several processes, including modulation of chemical synaptic transmission; regulation of action potential firing pattern; and response to ischemia. Part of presynapse. Biomarker of Alzheimer's disease. [provided by Alliance of Genome Resources, Apr 2022]
