A silent mutation is a mutation in a nucleotide sequence, which does not change the sequence of amino acids. Even regions outside the coding sequence could be affected by a silent mutation. In non-coding regions in DNA, the nucleotide sequence does not have bases needed for the protein required[1].

Silent mutations do not affect the phenotype as there are no change in amino acid sequence[2].
