Genes affected

IGSF9 (HGNC:18132): (immunoglobulin superfamily member 9) Predicted to enable cell-cell adhesion mediator activity. Predicted to be involved in axon guidance; dendrite self-avoidance; and homophilic cell adhesion via plasma membrane adhesion molecules. Predicted to act upstream of or within dendrite development and regulation of synapse organization. Predicted to be located in dendrite and inhibitory synapse. Predicted to be integral component of membrane. Predicted to be active in axon and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
