WebMar 18, 2024 · As one type of gene mutation, the frameshift is defined as protein translations that start not at the first, but at the second (+1 frameshift or +1 fs) or the third (–1 frameshift or –1 fs) of the codon. Due to the triplet nature of codons, the amino acid sequence of a protein is determined by contiguous triplets. WebApr 9, 2024 · Due to the triplet nature of the genetic code, an insertion or deletion can change the reading frame for the entire subsequent sequence. For example, if a particular sequence is read sequentially (Figure 4). Figure 4. Impact of frameshift mutation on gene function. The normal gene sequence is shown in part A.

WebOct 19, 2024 · Based on the location and extent of the mutations, different exons have to be skipped to restore the reading frame [ 11, 12 ]. Since about two-thirds of patients carry a deletion involving one or more exons, the ‘applicability’ per exon is largely determined by the location of these deletions [ 12, 13 ]. WebThis tool identifies all open reading frames using the standard or alternative genetic codes. The deduced amino acid sequence can be saved in various formats and searched against the sequence database using the basic local alignment search tool (BLAST) server.
