Copy number variation (CNV) is a general term used to describe a molecular phenomenon in which sequences of the genome are repeated, and the number of repeats varies between individuals of the same species.

CNL denotes the decreased gene (or sequence fragment) copies in the genome while CNG denotes the gain of additional gene copies in the human genome.

Recent evidence also suggests that changes in copy number play an important role in evolution. For example, a comparison of the human and chimpanzee genetic sequences found that copy number changes account for more differences between the two species than do other forms of mutation (Cheng et al., 2005).

Copy number variation (abbreviated CNV) refers to a circumstance in which the number of copies of a specific segment of DNA varies among different individuals' genomes.

One of the most well-known examples of a disease-causing CNV is Huntington disease, which is caused by a repeating sequence of three base pairs (known as a trinucleotide repeat) at the end of the coding region of the HTT gene.

Copy number variation is defined as the presence of variable numbers of copies of a particular DNA segment relative to a reference genome. Deletions and duplications result in copy number changes.

CNVs are divided into two major groups: copy number loss (CNL) and copy number gain (CNG). CNL denotes the decreased gene (or sequence fragment) copies in the genome while CNG denotes the gain of additional gene copies in the human genome.

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.

A genomic location where there is a change from one copy number state to another is called a copy number change point. To identify copy number change points and copy number states, a DNA sample from each of the target and the reference genotypes is obtained.
