Listen up, folks, we’ve got something huge here. We’re talking about the big question in genomics – how common and rare variants play together in the game of complex traits. It’s a big deal, believe me. And we’ve got the UK Biobank, a goldmine of data, to thank for this breakthrough. We’re using the latest and greatest – whole-exome sequencing and genome-wide association studies – to crack this code.
Now, we’ve come up with this incredible metric, the CORAC signature. It’s like a scorecard for how these genetic players – common and rare – team up. And guess what? The more data we have, the clearer the picture. It’s all about the power, the sample size. Bigger is better, and the numbers prove it – a massive correlation (Spearman ρ = 0.594, P < 2.2e - 16). That's right, more power means more convergence of genetic variation. It's a fact.
And we didn’t just take a quick look and call it a day. No, we did our homework – sensitivity analyses, simulations – the works. We made sure this thing is solid. Negative selection? It tries to play tough, but it actually makes the convergence signature even clearer. This is a game-changer for finding associations and hunting down new drugs.
So, what we’ve got here is a roadmap, a blueprint for the future of whole-genome sequencing. We’re shining a light on the path forward after genome-wide association studies. It’s going to be terrific for fine-mapping and drug discovery. We’re making genomics great again, one variant at a time!
