Reading frame mutation

The usage of multiple reading frames leads to the possibility of overlapping genes; there may be many of these in viral, prokaryote, and mitochondrial genomes. Some viruses, e.g. hepatitis B virus and BYDV, use several overlapping genes in different reading frames. In rare cases, a ribosome may shift from one frame to another during translati… WebApr 3, 2024 · This exon was selected because the neighboring exon 45 is the single exon most commonly deleted 24; in theory, in patients with exon 45 mutations, skipping of exon 44 should restore the open reading frame to allow translation of a partially functional dystrophin protein and result in less severe disease. 24 It will be anticipated that NS-089 ...
