Genes affected

ARHGAP18 (HGNC:21035): (Rho GTPase activating protein 18) Enables GTPase activator activity. Involved in several processes, including regulation of actin filament polymerization; regulation of small GTPase mediated signal transduction; and small GTPase mediated signal transduction. Located in cytosol; nuclear speck; and plasma membrane. Part of cytoplasmic microtubule and ruffle. Implicated in schizophrenia. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.294 is higher than 0.05.
