  • This take-away point is extremely important given that an identified actionable mutation in another solid tumor may not necessarily translate to be an actionable mutation in breast cancer. (medpagetoday.com)
  • Testing for epidermal growth factor receptor ( EGFR ) mutations is part of the current standard of care in advanced non-small cell lung cancer. (bmj.com)
  • More regional cancer genomic initiatives and public availability of this data are needed in order to develop more precise oncology in locally advanced breast cancer. (ecancer.org)
  • W]e adapted an additive effects model from complex trait studies to show that the aggregated effect of putative passengers, including undetected weak drivers, provides significant additional power ([around 12 percent] additive variance) for predicting cancerous phenotypes, beyond PCAWG-identified driver mutations," the authors explained.

  • The classic examples of necessarily be processed by the cel replication fidelity can confer strong chemical agents that require met- into a mutation (see Chapter 12, by mutator phenotypes that result in ge- abolic activation to become carci- DeMarini). (who.int)
  • A deleterious mutation may be much more or less deleterious depending on the absence or presence of other mutations. (uncommondescent.com)
  • Therefore, as mutations accumulate, each new mutation has a greater and greater average fitness deleterious effect. (uncommondescent.com)
  • Genetic analyses have provided a wealth of information on the genectic constitution of STT, and clearly nonrandom patterns of genetic changes, ranging from point mutations and gene fusions to massive genomic imbalalnces, have been identified in each histological entity studied in sufficient detail.

  • Based on our findings, we propose that IFSA is a potential threat to genomic stability in eukaryotes. (elifesciences.org)
