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]

Ambry Genetics

Oct 19, 2024

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
