A point mutation that does not result in a change to the amino acid coded for is said to be a synonymous mutation.
There is a change in the DNA sequence which codes for the amino acid in the sequence for protein but the amino acid that is being encoded does not change. Redundancy occurs in the genetic code which means multiple codons can code for the same amino acid but the change or the mutation occurs at the third position of the codon and the amino acid to be incorporated remains same at the particular position of the protein sequence.
