Use of Affymetrix mapping arrays in the diagnosis of gene copy number variation.
Diagnosing constitutional pathogenic copy number variants requires measuring the submicroscopic segmental chromosomal imbalance. The Affymetrix GeneChip mapping array has been used to measure duplication and deletion of genetic material in DNA samples. This protocol describes the measurement and analysis processes, specifically the computational analyses that are involved in identifying pathogenic copy number variants.
