Laboratory Director, Emory Genetics Laboratory, Atlanta, Georgia, USA
In this talk, Lora J. Bean, PhD, FACMG, presented valuable insights into the use of microarrays and NGS in parallel for CNV detection.
The Laboratory Director of Emory Genetics emphasised that while CNV calls from NGS data are becoming increasingly popular, they must be confirmed due to the significant false positive rate associated with them.

One of the critical points Lora highlighted was that CNV detection varies based on coverage, quality, and sequence context. Some regions are easier to detect than others, and the larger the CNV, the greater the accuracy of CNV detection. Additionally, the detection of CNVs involving single exons versus multiple exons can also affect the reliability of CNV calls.
Although NGS data has its advantages, microarray data is still considered more reliable for CNV detection as array technology is a reliable and established technology. Additionally, the reliability of CNV detection can vary based on coverage, quality, and sequence context. As such, the use of microarray technology remains a reliable option for CNV detection in exome sequencing context.
