Notably, the knock-out experiments and the genetic diseases demonstrated that mutations in keratin genes often (depending on the locus of mutation within the keratin molecule) cause more severe defects than the complete loss of a keratin gene whose failure might be compensated if available at this site by another/other keratin/s.
Since the pairings of splice sites and gene architecture were supposed to be associated with intron exon recognition, it is likely that the preferred loci of mutations occurring with the evolution of cardiotoxin genes would not affect the processing of cardiotoxin precursors.
Analyzing whole genome sequences for 68 mutation accumulation lines derived from 12 parental genotypes, reveals examples of mutator-allele-associated base-substitution biases, clustered mutations, and locus-specific patterns of mutations.
In addition, these authors reported cases where the distribution of mutational effects changed from many divergent loci with mutations of small effect to few loci with mutations of large effect.
Reports of Drosophila sodium pump mutants with stress-sensitive paralysis and ouabain sensitivity (Lebovitz et al. 1989), and later those with temperature-dependent paralysis, reduced longevity and neural degeneration (Palladino et al. 2003), suggested that sodium pump loci were capable of mutations that could result in neurological disease-like states, at least in invertebrates.
The estimates for σ θ anc implied that most of the variation across loci of the mutation rate u was between 7.7 × 10−4 and 3.5 × 10−3.
More importantly, YAP activation has been found in human cancers such as HCC, neurofibromatosis 2 and uveal melanoma due to amplification of the YAP gene locus or mutations of NF2 or GNAQ/ GNA11.
We plan to use a high throughput 454 sequencing technology that may identify or eliminate this locus as the locus of the chondrodystrophy mutation.
Application of our improved measure of biological information to evolution on two-locus, two-allele fitness landscapes demonstrates that mutual information between loci reflects epistatic interaction of mutations.
This is because once a loss of function mutation occurs at any regulatory locus of a signaling pathway, mutations in its member genes and downstream FGUs may be relieved of selection pressure, except those having multiple functions.
However, the authors have shown the difference of mutation locus of gun4 I (earlier identified) and gun4 II (in this study) and also the differences of light sensitivity and chlorophyll content which is very interesting.
