WebFour classes of mutations are (1) spontaneous mutations (molecular decay), (2) mutations due to error-prone replication bypass of naturally occurring DNA damage (also called error-prone translesion synthesis), (3) errors introduced during DNA repair, and (4) induced mutations caused by mutagens. WebSep 12, 2024 · Middle, Schematic showing eteplirsen-mediated reading-frame correction of a DMD frameshift mutation. The normal dystrophin locus from exons 41 to 52 is shown, indicating the reading frame of each exon. Many patients with DMD have variable-sized deletions spanning exons 47 to 50, disrupting the reading frame (dashed blue line).

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.
