Targeting defects in the DNA repair machinery of neoplastic cells, for example, those due to inactivating BRCA1 and/or BRCA2 mutations, has been used for developing new therapies in certain types of breast, ovarian and pancreatic cancers. Recently, a mutational signature was associated with failure of double-strand DNA break repair by homologous recombination based on its high mutational burden...

Traditional sequence comparison by alignment applies a mutation model comprising two events, substitutions and indels (insertions or deletions) of single positions (SI). However, modern genetic analysis knows a variety of more complex mutation events (e.g., duplications, excisions and rearrangements), especially regarding DNA. With the ever more DNA sequence data becoming available, the need to...

Genome evolution is shaped by a multitude of mutational processes, including point mutations, insertions, and deletions of DNA sequences, as well as segmental duplications. These mutational processes can leave distinctive qualitative marks in the statistical features of genomic DNA sequences. One such feature is the match length distribution (MLD) of exactly matching sequence segments within an...

background: mitochondria are autonomous cellular organelles that oversee a variety of functions such as metabolism, energy production, calcium buffering, and cell fate determination. most recently, mitochondrial dysfunction caused by mitochondrial mutations played important roles in the pathogenesis of asthma. however, the frequency of mitochondrial trna mutations in asthma is largely unknown. ...
