摘要

The advent of single cell DNA sequencing revealed astonishing dynamics of genomic variability, but failed at characterizing smaller to mid size variants that on the germline level have a profound impact. In this work we discover previously uncharacterized genomic dynamics in 18 cells from three human brains utilizing single cell long-read whole genome sequencing. This provides key insights into the dynamic of the genomes of individual cells and further highlights brain specific activity of transposable elements, but requires validation in larger studies.
