Abstract
Genomic variants that are acquired during a lifetime as a result of development, environmental exposure, and aging are present in every cell of the human body. While some variants are shared between cells, most of them are not. Therefore, analyzing the nuclear genome of a cell is the ultimate way to study genomic mosaicism. However, comprehensive evaluation of variations in a single cell's genome is not yet possible due to unresolved technical issues, while the analysis of a bulk of cells can provide a valuable insight into mosaicism in a studied sample. Here, we describe, compare, and discuss strategies, experimental techniques, and analytical methods for discovery of a spectrum of mosaic variants from a bulk of cells and from single cells. We specifically focus on next-generation sequencing technologies for genome analysis as they enable the discovery of mosaic variants of all types.
