Reversion

reversion

(Science: molecular biology) Reversion of a mutation occurs when a second mutation restores the function that was lost as a result of the first mutation. The second mutation causes a change in the dNA that either reverses the original alteration or compensates for it. A reappearance of an earlier characteristic.

protein sequence

... mutations--which may or may not have an effect on function--is the mutant also a frameshift mutation? If it is, then, unless there is a nearby reversion back to the correct reading frame, then the mutant is very likely non-functional. But that's only IF the dropped G is meant to indicate a ...
