Definitions for "Suppressor gene"
A mutated gene which produces a product which reverses the effect of a previous specific mutation without actually correcting the original mutation in the DNA can be either intergenic or intragenic.
A gene that exhibits the transformed (malignant) phenotype, usually associated with dominant negative regulation of cell proliferation or cell migration. Often it is mutated or deleted in transformed cells and cancer.
A gene that, when mutated, apparently restores the wild-type phenotype to a mutation at another locus.
