missense mutation
Quick Summary
A missense mutation is a type of gene mutation where a single base pair change in the DNA sequence alters a codon. This alteration results in a different amino acid being incorporated into the protein during translation.123
These mutations can lead to changes in the protein's structure and function, potentially causing a loss of function or altered activity. Missense mutations are a subset of point mutations, which involve a change in a single nucleotide pair. While most missense mutations occur spontaneously due to errors in DNA replication, they can also be induced by environmental factors like radiation.12

…amino acid are called “missense” mutations; these can lead to alteration or loss of protein function. A more severe type of base substitution, called a “nonsense” mutation, results in a stop codon in a position where there was not one before, which causes the premature termination of protein synthesis…

point mutation…are divided into silent mutations, missense mutations, and nonsense mutations. Silent mutations result in a new codon (a triplet nucleotide sequence in RNA) that codes for the same amino acid as the wild type codon in that position. In some silent mutations the codon codes for a different amino acid…
