The phrase "alterations copy" is correct and usable in written English.
It can be used in contexts related to editing or revising documents, indicating a version of a text that has been modified or altered.
Example: "Please review the alterations copy of the manuscript and provide your feedback by the end of the week."
Alternatives: "revised copy" or "edited version".
Molecular genetic studies of lung cancer have revealed that clinically evident lung cancers have multiple genetic and epigenetic abnormalities, including DNA sequence alterations, copy number changes, and aberrant promoter hypermethylation.
Moreover, large scale sequencing studies have revealed the various intragenic alterations, copy number variants and chromosomal rearrangements that characterize the many distinct types of cancer [ 48].
Taken together, the data suggest that genetic and epigenetic alterations (copy number alterations and DNA methylation alterations) are not mutually exclusive during urothelial carcinogenesis.
We determined the number and type of copy number changes in each tumor by counting three types of copy number alterations; copy number changes involving whole chromosomes, low level gains and losses affecting extended portions of chromosomes, and amplifications defined as focal regions of increased copy number [ 14].
CNA: copy number alteration; CNVs: copy number variations; DDR: DNA damage response; FACS: fluorescence-activated cell sorting; miR: microRNA.
This jeopardizes the detection of two important classes of alteration: copy-neutral and deletion-associated LOH.
Cancer and other genetic diseases are characterized by genome alterations, including DNA copy number changes.
Genomic alterations found in malignancies are somatic mutations, chromosomal translocations and copy number alterations (CNA).
Most genetic changes were in the form of somatic copy number alterations, which were predominantly copy number gains, but the genes associated with these copy number alterations have yet to be identified [ 161].
Alterations in copy number were widely shared, suggesting they occurred early in carcinogenesis, while point mutations appeared to evolve gradually over a longer period of time.
As seen with other types of cancer, ALL carcinomas were characterized by distinct clonal populations of cells where alterations in copy number preceded the occurrence of SNVs.
