Genes affected

IQSEC3 (HGNC:29193): (IQ motif and Sec7 domain ArfGEF 3) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in several processes, including actin cytoskeleton organization; activation of GTPase activity; and regulation of small GTPase mediated signal transduction. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
