Abstract

Developments in microarray and high throughput sequencing (HTS) technologies have resulted in a rapid expansion of research into epigenomic changes that occur in normal development and in the progression of disease, such as cancer. Not surprisingly, copy number variation (CNV) has a direct effect on HTS read densities and can therefore bias differential detection results. We have developed a flexible approach called ABCD-DNA (Affinity Based Copy-number-aware Differential quantitative DNA sequencing analyses) that integrates CNV and other systematic factors directly into the differential enrichment engine.
