Genes affected

NGEF (HGNC:7807): (neuronal guanine nucleotide exchange factor) Enables guanyl-nucleotide exchange factor activity. Predicted to be involved in several processes, including activation of GTPase activity; ephrin receptor signaling pathway; and negative regulation of dendritic spine morphogenesis. Predicted to be located in cytosol. Predicted to be active in glutamatergic synapse. [provided by Alliance of Genome Resources, Apr 2022]
