Silent mutation

Definition

noun, plural: silent mutations

A form of point mutation resulting in a codon that codes for the same or a different amino acid but without any functional change in the protein product.


Supplement

Silent mutations do not cause changes in the amino acid sequence and hence the protein is still functional. Because of that they are regarded as though they are evolutionarily neutral.


Compare: nonsense mutation, missense mutation
See also: point mutation
