Ancestral Differences Affect Performance of CRISPR-Cas9 Guides in Human Cells

New research shows that many of these CRISPR screening experiments rely on components, called CRISPR/Cas9 guides, that do not perform equally well in cells from people of all ancestries, which can cause CRISPR screens to miss cancer dependencies.
