An adequate mutation frequency is required to keep the number of PCR reactions associated with TILLING to a manageable number.
In conclusion, irrespective of whether an increased mutation frequency is strictly required for P. aeruginosa pathoadaptation in CF, the ability of this pathogen to display a reversible mutator phenotype likely contributes to airway colonization, persistence, and pathoadaptation, particularly under conditions of ROS-induced stress.
The consequences of EPEC induced MMR protein downregulation on spontaneous and induced mutation frequency rates therefore requires investigation.
Further study correlating serum oestradiol, testosterone levels and PIK3CA mutation frequency in MBCs are required to further elaborate on a possible association.
In each subset, we required a minimum mutation frequency of 5%.
Due to the low RAD51C mutation frequency, however, large collaborative studies are required to quantify the relative risk of RAD51C alterations for BC and potentially other cancer entities and, most importantly, to unravel genotype phenotype correlations as well as genetic modifying factors that determine phenotypic variability with respect to cancer site and tumor subtype.
SoDA2 selects IGHD1∼26*01 requiring three mutations (8.5% mutation frequency in CDR3) and seven n-nucleotides, while IGHD7∼27*01 requires two mutations (5.5% mutation frequency) and 10 n-nucleotides.
As a consequence, multiple empirical mutation frequencies measurements will be required to obtain a more precise determination of true mutation frequencies.
In Till et al. (2007), the authors argued that efficient TILLING requires a population with mutation frequency of ≥ 1 mutation/500 kb to ensure that at least one mutation is found per gel run in the LI-COR DNA analyzer.
Yeast-null mutants of RAD27 (RTH1) Flap endonuclease, an enzyme required for lagging strand DNA synthesis and DNA repair, display an increased microsatellite mutation frequency and a mutational bias favoring expansion mutations within [GT/CA] microsatellites.
