Copy number variation

Copy number variations (CNVs) represent of class of variation in which segments of the genome can be duplicated (gains) or deleted (losses). Inherited de novo CNVs (up to ~10 Mb) have been associated with many disease research conditions, including cancer research, and inherited disorders research.

Why copy number matters

CNVs lead to a variety of phenotypic impacts: deletions can unmask recessive mutations, duplications and deletions can alter the copy number of dosage-sensitive genes, deletions can result in position effects that alter the expression or regulation of genes, and selection of duplicated regions containing gain-of-function driver mutations can occur in cancer.

Inherited and de novo CNVs of chromosomal regions have been associated with many debilitating diseases, including birth defects and cancer, and have been associated with hemizygous or homozygous gains or losses of chromosomal material.

Single workflow for the detection of CNVs

There are multiple default workflows in Ion Reporter™ Software for single samples or paired samples when using Ion AmpliSeq™ gene panels that simultaneously detect copy number variation, SNPs, and indels in a single run. The workflows are easily customizable and have 3 sensitivity settings to allow flexibility in experimental design. All use a Hidden Markov Model (HMM) algorithm for copy number detection.

Copy Number Variants can be now be detected using ready-to-use and custom Ion AmpliSeq™ panels and the Ion Reporter™ Software.
