difference between specimens Explanation: It is talking about the calculation of a proportion/ratio: For a certain gene locus （基因位点）, some mutations at it may be detected. If we want to calculate the proportion (or, rate of occurrence) of a certain mutant, we can divide the detected amount of the mutant by the total number of all types of the gene locus, i.e. "(mutated type + wild type)" （突变型+野生型）. 野生型 means those most commonly seen in samples/specimens and thus were taken as the normal type. For 突变丰度（mutation abundance）, it is the amount of mutation(s) detected in a certain sample/specimen. If the specimen contains only a bit of tumor cells or the tumor cells in that rarely contain mutations, the mutation abundance of it will be low. So it is why the source text said "突变丰度受肿瘤细胞含量和取材等因素的影响" to readers. I think 取材 here means 取材差异, referring to differences among specimens collected from different sites of a tumor, or through different sampling methods.

Here it explains the (relative) proportion of a certain mutated type occurred in all types of the gene locus, both normal and mutated. 2. Yes, since the source text uses "即等于", lit. "(that is) equal to" to connect the two parts of the sentence, I think it is fine to translate it in a form of equation/formula. However its calculation is simply stated as "突变型/ (突变型+野生型)", and is not accurate enough, some extra clarification may need to be added ;) |
