Nonsynonymous substitution

Nonsynonymous substitution

A nonsynonymous substitution is a nucleotide mutation that alters the amino acid sequence of a protein. It is contrasted with synonymous substitutions which do not alter amino acid sequences. As nonsynonymous substitutions result in a biological change in the organism, they are subject to natural selection.
