Several diseases have frameshift mutations as at least part of the cause. Knowing prevalent mutations can also aid in the diagnosis of the disease. Currently there are attempts to use frameshift mutations beneficially in the treatment of diseases, changing the reading frame of the amino acids. Frameshift mutations are known to be a factor in colorectal cancer as well as ot… WebHowever, frameshift mutation s, caused by insertions or deletions of a number of nucleotides that are not a multiple of three are extremely problematic because a shift in the reading frame results (Figure 11.18). Because ribosomes read the mRNA in triplet codons, frameshift mutations can change every amino acid after the point of the mutation.
Effects of Frameshift Mutations: Definitions and Examples
WebNov 4, 2024 · A frameshift variant occurs when there is an addition or loss of nucleotides that shifts the grouping and changes the code for all downstream amino acids. The resulting protein is usually nonfunctional. Insertions, deletions, and duplications can all be frameshift variants.
