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]

Jul 25, 2023

The c.1030A>C (p.M344L) alteration is located in exon 6 (coding exon 6) of the RIC8A gene. This alteration results from a A to C substitution at nucleotide position 1030, causing the methionine (M) at amino acid position 344 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
