Genes affected

ARL3 (HGNC:694): (ADP ribosylation factor like GTPase 3) Enables GDP binding activity; GTP binding activity; and microtubule binding activity. Involved in several processes, including cilium assembly; protein localization to cilium; and small GTPase mediated signal transduction. Acts upstream of or within post-Golgi vesicle-mediated transport. Located in several cellular components, including microtubule cytoskeleton; midbody; and photoreceptor connecting cilium. Implicated in Joubert syndrome and retinitis pigmentosa 83. [provided by Alliance of Genome Resources, Apr 2022]
