Copy number analysis is the process of analyzing data produced by a test for DNA copy number variation in an organism's sample. One application of such analysis is the detection of chromosomal copy number variation that may cause or may increase risks of various critical disorders.

The term copy number refers to the number of copies of a particular plasmid per chromosome present in a cell or the number of copies of a gene in the genome of an organism. See medical definition.

Copy number variation, or CNV, refers to the duplication or deletion of stretches of a chromosomal region. These can be as large as megabases or smaller than 1,000 base pairs. Studies have linked copy number variation to a higher risk of developing several disorders, including autism.

Copy number polymorphisms can affect gene expression through complex mechanisms that extend beyond simple gene dosage effects, and include, for example, insertion and deletion of gene regulatory regions and alterations of physical proximity of genes and regulatory elements.

Definition of copy number : a numeral placed on a book to distinguish it from other copies of the same title.

Copy number variants (CNVs) are where the number of repeats varies between individuals, and may account for almost 10% of an individual's genome. Many of these variants appear to have no effect on health, but some are associated with disease, or can have other clinically relevant effects.
