Before revision: Synthetic rescue (or synthetic recovery or synthetic viability when a lethal phenotype is rescued ) refers to a genetic interaction in which a cell that is nonviable, sensitive to a specific drug, or otherwise imparied due to the presence of a genetic mutation becomes viable when the original mutation is combined with a second mutation in a different gene.
