Genes affected

PLXNA4 (HGNC:9102): (plexin A4) Predicted to enable semaphorin receptor activity. Predicted to be involved in several processes, including axon guidance; positive regulation of axonogenesis; and regulation of GTPase activity. Predicted to act upstream of or within several processes, including nervous system development; regulation of axon extension involved in axon guidance; and regulation of negative chemotaxis. Predicted to be located in plasma membrane. Predicted to be part of semaphorin receptor complex. Predicted to be integral component of plasma membrane.
