MSH: A type of mutation in which a number of NUCLEOTIDES deleted from or inserted into a protein coding sequence is not divisible by three, thereby causing an alteration in the READING FRAMES of the entire coding sequence downstream of the mutation. These mutations may be induced by certain types of MUTAGENS or may occur spontaneously.,CSP: insertions or deletions of genetic material that lead to a shift in the translation of the reading frame; the mutation usually leads to nonfunctional proteins.,NCI: An insertion or deletion involving a number of base pairs that is not a multiple of three, which consequently disrupts the triplet reading frame of a DNA sequence. Such mutations usually lead to the creation of a premature termination (stop) codon, and result in a truncated (shorter-than-normal) protein product.,NCI: A mutation occuring within the protein-coding region of a gene which results in a shift in the reading frame of the encoded protein. Frameshift mutations often result in the premature truncation of
