Genes affected

RIC8A (HGNC:29550): (RIC8 guanine nucleotide exchange factor A) Predicted to enable G-protein alpha-subunit binding activity; GTPase activator activity; and guanyl-nucleotide exchange factor activity. Predicted to be involved in G protein-coupled receptor signaling pathway. Predicted to act upstream of or within several processes, including basement membrane organization; gastrulation; and visual learning. Predicted to be located in membrane. Predicted to be active in cytoplasm and plasma membrane. [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=-0.81).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.552 is higher than 0.05.
