Genes affected

SHISA7 (HGNC:35409): (shisa family member 7) Predicted to enable GABA receptor binding activity and ionotropic glutamate receptor binding activity. Predicted to be involved in several processes, including gamma-aminobutyric acid receptor clustering; regulation of signaling receptor activity; and regulation of synaptic plasticity. Predicted to be located in asymmetric, glutamatergic, excitatory synapse. Predicted to be part of AMPA glutamate receptor complex. Predicted to be active in glutamatergic synapse; postsynaptic density; and synaptic membrane. Predicted to be integral component of postsynaptic specialization membrane.
