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]

IQSEC3-AS2 (HGNC:56741): (IQSEC3 antisense RNA 2)

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.813 is higher than 0.05.
