Rao, J., Peng, L., Liang, X. et al. (2020) assessed the efficacy for detecting copy number variations (CNV) using whole-genome sequencing with the DNBSEQ™ platform. In previous studies they had verified the platform’s efficacy for detecting single-nucleotide variants (SNVs) and insertions/deletions; this study focused on CNV detection. Results indicate that CNV detection capability on DNBSEQ™ is comparable to other platforms such as Illumina™ in terms of quantity, length, distribution, sensitivity and genome-wide accuracy. Moreover, DNBSEQ™ platforms are highlighted as providing a more accurate view of smaller CNVs. Rao, J., Peng, L., Liang, X. et al. (2020).
