A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three.
The earlier in the sequence the deletion or insertion occurs, the more altered the protein. A frameshift mutation is not the same as a single-nucleotide polymorphism in which a nucleotide is replaced, rather than inserted or deleted.A frameshift mutation will in general cause the reading of the codons after the mutation to code for different amino acids.The frameshift mutation will also alter the first stop codon (UAA, UGA or UAG) encountered in the sequence.The polypeptide being created could be abnormally short or abnormally long, and will most likely not be functional.he frameshift mutation will also alter the first stop codon (UAA, UGA or UAG) encountered in the sequence.
