Flanking microhomology
WebSep 20, 2024 · Some cases involve a minimal loss of flanking sequence, with a normal phenotype resulting if the repeat number is now in the normal range [12,13,14,15]. ... Such MHs are the hallmarks of a process known as microhomology mediated end joining (MMEJ). As illustrated in Figure 3B, ... WebJan 13, 2024 · A subset of A-NHEJ relies on microhomologous sequences on either side of the DSB, thus is named as microhomology-mediated end joining (MMEJ) [10–12]. MMEJ is a mutagenic DSB repair mechanism, which always associates with deletions flanking the break sites and contributes to chromosome translocations and rearrangements.
