Readthrough mutation example
WebJan 31, 2024 · In patients with hemophilia A, nonsense mutations potentially sensitive to readthrough agents represent approximately 16% of the point mutations. The aim of this study was to measure the readthrough effect of different compounds and to analyze the influence of premature termination codon context in selected nonsense mutations … WebFor example, a mutation in the tRNA that recognizes the amber stop codon allows translation to "read through" the codon and produce a full-length protein, thereby …

WebJan 13, 2024 · A missense mutation occurs when there is a mistake in the DNA code and one of the DNA base pairs is changed, for example, A is swapped for C. This single change means that the DNA now encodes for a different amino acid, known as a substitution. Sometimes a change in the amino acid has no effect on the resulting protein's function at … WebMar 23, 2024 · For example, when a cytosine is found at the +4 position (the nucleotide immediately following the stop codon), basal readthrough levels are increased [6,7,11]. Additionally, other positions surrounding the stop codon seem to have an influence on readthrough levels [ 8 ], as does the secondary structure of the mRNA [ 18 , 22 , 23 ].
