Direct To Consumer Dna Testing For Copy Number Variation

Copy Number Analysis

Copy number analysis refers to the assessment of variations in the number of copies of DNA sections, utilizing tools for data segmentation, copy number state assignment, loss of heterozygosity determination, and visualization of copy number variants (CNVs) from next-generation sequencing data.

The nice thing about qPCR is that since it measures relative quantification - that is, since you're looking at the amount of DNA in your sample relative to your normal control - you can set up your calculations so that your assay output number (RQ value) matches the copy number of your sample.

In this article I review the current microarray technologies being used for genome-wide CNV detection and for the association of CNVs with normal and disease phenotypes. One of the main methods by which CNVs can be identified using DNA microarrays is comparative genomic hybridization (CGH).
