WebFrameshift mutations in microsatellites can be identified by extraction of DNA from both normal and tumor tissue (usually paraffin-embedded tissue), amplification of selected … WebHowever, a frameshift or nonsense mutation that occurs near the 3' end of the gene might allow the protein to retain the ability to function. Silent mutations are least likely to affect protein function. Missense mutations are often difficult to predict. If the change is to a similar amino acid or in a non-critical amino acid, the mutation ...
