What can we learn about a single rare variant? Published today in Science: the 23andMe Research Institute and Dana-Farber studied the EGFR T790M in 10.1M 23andMe research participants. The variant has OR = 25.2 for lung cancer, rising to 61.7 in never-smokers(!). 🧵

'Long-read de novo assembly of “noisy” nanopore reads outperforms state-of-the-art variant calling by an order of magnitude, even when restricted to regions syntenic to GRCh38.' ... They completed the human genome with a missing 15%... 🤯 And other vertebrates!
