Rarely in the entire history of science, has QC been a topic of such passion, importance and impact. If only the French and Americans had adopted such rigor when they messed up the design of that multi billion $ telescope because one was using the metric system, the other the imperial system.
New paper on everyone’s favourite topic, QC!
We show why you should do genotype-level QC on your WGS data

Very real quotes about this paper -
“The most exciting, mind-blowing paper of the year!”
“On a par with Fisher 1918”

This led us to identify a novel NDD associated with biallelic RNU4-2 variants, with a phenotype distinct from ReNU 🤯
