As far as dominant mutations are concerned, these are often de novo events, as was previously described in patients with congenital hypomyelinating neuropathy or Dejerine Sottas neuropathy (Gabreels-Festen, 2002; Plante-Bordeneuve and Said, 2002).
The 2009 increase in ST-1655 (cc23), which all harbored lpxL1 mutations, is concerning because of its preponderance for causing meningitis in healthy young persons.
Beneficial mutations were ignored because we were concerned with the possible deterioration or maintenance of initially well-adapted genomes, for which the frequency of beneficial mutations is likely to be rare (Maynard Smith 1978; Charlesworth et al. 1993; cf. Goyal et al. 2012).
However, we were concerned that these mutations may affect the binding of C/EBP, a known regulator of IL8 because the E-box sequence heavily overlaps with the C/EBP binding site [ 25].
For example, studies that seek to discover novel CD8+TL escape or drug resistance mutations may be concerned with whether certain low-frequency variants represent artifacts or real mutations (Wang et al. 2007).
To the best of our knowledge, ours is by far the largest sample as far as the studies of PR mutations in RSA are concerned.
As far as NPM1 is concerned, mutations in this gene drive tumorigenesis in acute myeloid leukemia (AML) [ 60- 62], but its role in solid tumors has been controversial [ 63- 65].
However, it has not been addressed whether these variants differ from the standard genetic code as far as mutation and translation loads are concerned.
Overall, it seems that the combinations of different disease-causing mutations specific to each strain cause various degenerative diseases, which combinations are a cause of short life spans of SAMP strains as far as focusing on the mutations of the coding regions is concerned.
If you're concerned that there's some mutation out there, resulting in rodents of a gargantuan size, well... "I do not think there are any 3 pound rats in the city," Combs told The Huffington Post last week.
