Frameshift mutations, caused by insertions or deletions of a number of nucleotides that are not a multiple of three, lead to a shift in the reading frame of the genetic sequence. This shift alters the grouping of the nucleotides into codons, resulting in the production of entirely different amino acids from the point of mutation onwards, and can lead to multiple contiguous amino acid changes in the resulting protein.
