(Another by Nicole Gaudelli's team apparently coming soon.)

Why care:
Base editors can install predictable gene edits without DNA breaks. The described C-to-T editors are as efficient at current tools, but create less off-target damage in the genome and are smaller, which helps with delivery in vivo.

Improved cytosine base editors are created by repurposing an adenine deaminase.

Let's start with detection of large CRISPR edits.

Why care:
Often first questions after #CRISPR editing is: What mutations do I have? Unfortunately, that can be hard to answer. Target sites are typically PCR amplified and sequenced, but that has a strong survivor bias. PCR favors some sequences, creates chimeras and fails if primer site is deleted. This paper presents a workflow to mitigate some of these issues and get a more complete picture.
