Thus, the ΔΔ Go of the R58A mutation reflects the net free energy change of disrupting both these interactions.
Yet does this starting point, appearance of crippling mutation, reflect the starting point of natural evolutionary scenarios as we understand them?
On the other hand, assuming that the expected phenotype of a double mutation reflects the additional effects of the single mutations, E-MAP, an extension of SGA, gains power by identifying positive as well as negative interactions, which, in this case, would indicate that the double mutant is healthier than expected.
About 30% of all reactions and 19% of included genes were lethal mutations reflecting the inability of the perturbed network to synthesize essential components.
Manning also identified the inefficiencies existing in polyclonal populations that prevent sweeping of advantageous mutations, reflecting the reproductive isolation of clonal lines [ 17].
The fuzziness δ r1,2 t) and δγ(t) observed in fig. 2 e),2(f) decays on the larger time scale of compensatory mutations, reflecting the presence of such metastable states.
We have shown in our previous work on the BRCA1 and BRCA2 mutation spectrum of the Greek population that four BRCA1 mutations account for 54% of all mutations detected in both genes, whereas the rest are unique or low-frequency mutations, reflecting the population's genetic heterogeneity (Konstantopoulou et al, 2008).
The procedure, therefore, attempts to reconstruct partial allele sequences based on their closest phylogenetic relatives with known intron sequences, using the fact that intronic variability in HLA is characterized by highly systematic mutations reflecting the ancestral lineage of the alleles (Blasczyk et al., 1997).
In this study, the three AT heterozygote cell lines carrying a missense mutation had higher levels of mRNA levels, as measured by a semiquantitative PCR-based technique compared to the lines carrying truncating mutations, reflecting the observations in ATM homozygote lines.
The high rate of homozygous mutations (reflecting the high rate of consanguinity) may potentially offer further insights on genotype-phenotype correlation Wilson's disease (WD) is a rare autosomal recessive disorder of copper metabolism, with a prevalence of about 1 in 30 000 people.
