Abstract

Copy number variations (CNVs) in the genomes have been suggested to play important roles in human evolution, genetic diversity, and disease susceptibility. A number of assays have been developed for the detection of CNVs, including fluorescent in situ hybridization (FISH), array-based comparative genomic hybridization (aCGH), PCR-based assays, and next-generation sequencing (NGS). In this chapter, we describe a microarray method that has been used for the detection of genome-wide CNVs, loss of heterozygosity (LOH), and uniparental disomy (UPD) associated with constitutional and neoplastic disorders.

Keywords: Array-based comparative genomic hybridization (aCGH); Copy number variation (CNV); Loss of heterozygosity (LOH); Microarray; Single nucleotide polymorphism (SNP); Uniparental disomy (UPD).
