Genes affected

IGSF9B (HGNC:32326): (immunoglobulin superfamily member 9B) Predicted to enable kinase binding activity. Predicted to be involved in synaptic membrane adhesion. Predicted to act upstream of or within homophilic cell adhesion via plasma membrane adhesion molecules and positive regulation of inhibitory postsynaptic potential. Predicted to be located in dendrite; inhibitory synapse; and neuronal cell body. Predicted to be active in GABA-ergic synapse; neuron projection; and postsynaptic specialization of symmetric synapse.
