Frameshift Mutationdoi:10.1007/978-1-4020-6754-9_6217Insertion or deletion of bases changing the reading frame of the code words, leading to new amino acid sequences from the site toward the carboxyl end of the polypeptide (see Fig. F44). If one or two......
However, depending on the point at which division into codons begins, the nucleic acid can be read in three distinct phases or reading frames, and the sequence does not contain punctuation signals to indicate which frame should be used. A frameshift mutation is an insertion or deletion in the...
Insertion and deletion In addition topoint mutation,DNA replicationcan lead to the introduction of small insertions or deletions. The addition or removal of one or more base pairs leads to insertion or deletion mutations, respectively. As illustrated inFig. 2.18, the loss or addition of a single...
In the affected cancer cells, this results in insertion or deletion mutations at short, repetitive DNA sequences referred to as microsatellites. Such mutations in coding microsatellites (cMS) cause translational frameshifts that may destroy gene function. These frameshift mutations could also cause the...
Frequencies of nucleotide insertion opposite the lesion and chain extension from the 3'-primer terminus were established by steady state kinetic analysis. The ability of a damaged nucleotide to generate one-base and two-base frameshift deletions was determined primarily by two parameters: the nature ...
frame·shift mutation (frām′shĭft′) n. A mutation in a DNA chain that occurs when the number of nucleotides inserted or deleted is not a multiple of three, so that every codon beyond the point of insertion or deletion is read incorrectly during translation. ...
A deleterious frameshift insertion mutation in theZNF142gene leads to intellectual developmental disorder with impaired speech in three affected siblings: ...

carry a reported polymorphism (PKP2 p.E58D) whose pathogenic role, if any, remains to be investigated.18 Moreover, we cannot exclude that this proband could have a large insertion, deletion or mutation in the non-coding regions of ARVC/D genes or also a mutation in unknown ARVC/D genes....
The Iranome database also revealed the c.268G > A variant as a putative novel mutation in TMPRSS3. Conclusion This research expanded the pool of evidence regarding the association between mutations in the TMPRSS3 gene and ARNSHL. The finding confirmed that a single nucleotide deletion ...
In this study, we have used reversion of a -1 frameshift mutation within the same region of LYS2 to analyze the role of the MMR machinery in the correction of frameshift intermediates that give rise to insertion events. We found that insertion and deletion events occur at similar rates but ...
