Over the last years microarray technology has greatly improved the fields of structural genetic research and chromosomal disorders. Established cytogenetic and molecular techniques suffer of low resolution, limited to 5–10 megabases, like Giemsa-banded chromosome analysis, or are restricted in detecting only a few specific DNA regions like fluorescence in situ hybridization. Oligonucleotide microarrays containing millions of probes enabled the detection of sub-microscopic structural genetic variations, genome-wide, at ultra-high resolution down to a few hundred till thousand bases. Although high coverage next generation DNA sequencing can detect structural genetic variations, microarray screening is expected to be the main approach for several years due to its user-friendly workflow, lower cost and straightforward data interpretation.
This special issue invites contributions to the application and evaluation of microarrays for the discovery and diagnosis of structural genetic variations with a focus on Copy Number Variations (CNVs). These variations account for a substantial proportion of genetic variability in human and animal populations and range from seemingly neutral polymorphisms over polymorphisms correlating with phenotypic differences to pathological variations predisposing or causing disease.
It will be interesting to the reader of this special issue to increase the understanding of how microarray technology helped revealing the biological meaning of CNVs but also to learn about recent advances in CNV calling, database aided classification, and CNV phenotype correlations.

Abstract: Copy number variations (CNVs) are gains and losses of genomic sequence greater than 50 bp between two individuals of a species. Substantial progress has been made in understanding CNVs in humans and rodents. Since year 2008, at least 10 genome-wide cattle CNV studies have been published based on microarray technologies. In this review, we have systematically compared these bovine CNV results. The striking differences among different platforms and calling algorithms highlight the needs for standardizing array data collection, quality assessment and experimental validation. On the other hand, integration of CNV results with SNP and other datasets began to reveal impacts of CNVs on cattle domestication, health and production traits.
