MUTATION, French law. This term is synonymous with change, and is particularly applied to designate the change which takes place in the property of a thing in its transmission from one person to another; permutation therefore happens when, the owner of the thing sells, exchanges or gives it. It is nearly synonymous with transfer. (q.v.) Merl. Repert. h.t.

It is important to fully characterize the mutational spectrum and mutagenic specificity of daunomycin as a first step to better understand the antitumor and cardiotoxicity effects of this compound.
Such estimates, derived as ratios of standing genetic variance to the rate of mutational variance, are quite consistent with the results from laboratory mutation-accumulation experiments referred to above, as they imply average selection coefficients of heterozygous mutations of one to two percent.
The researchers found that patients with a high tumor mutational burden had significantly longer progression-free survival with nivolumab plus ipilimumab versus chemotherapy.
Nonetheless, the mutational burden of DM tumors may make them good candidates for immune checkpoint inhibitor therapy.
B: NRAS Mutational Analysis.--NRAS is mutated in approximately 20% of melanomas, with approximately 80% of mutations occurring in exon 3 at codons 60 and 61 and approximately 20% in exon 2 at codons 12 and 13.
A well-designed, targeted next generation sequencing panel can rapidly deliver comprehensive tumor mutational status, including the presence of rare variants, on limited amounts of formalin-fixed tissue.
They found that these cancer genomes had a much greater prevalence of the distinct mutational signature that is thought to be driven by the APOBEC family of genes.
TEHRAN (FNA)- Researchers provided the first comprehensive compendium of mutational processes that drive tumor development.
"Copper's rapid destruction of pathogens could prevent mutational resistance developing and also help reduce the spread of antibiotic resistance genes to receptive and potentially more virulent organisms," said Professor Bill Keevil, Head of the Microbiology Group and Director of the Environmental Healthcare Unit at the University of Southampton.
Some chapters offer detailed descriptions of research on mechanisms of cancer, in areas such as mutational analysis of the lung cancer genome, mechanisms of adrenocortical growth and tumorigenesis, mechanisms of B-cell lymphomagenesis, and the role of fibronectin in lung carcinoma cell growth.
Ninety percent of the offspring in each generation inherited the phenotype, a very high transmission frequency compared to that seen with genetic mutational events, which is typically 1% or less.
Because people mated most frequently with others from the same region, each population developed its own set of mutational differences, some influencing survival and some being just genetic quirks.
