Sure. Be happy to answer that. I mean [indiscernible] is not a company we know all that well, but they – our understanding is that there is nothing that differentiated about the exome there. Personalis started working on exomes 10 years ago, realized the fundamental problems that led to there being gaps in the sequencing that many genes have regions that are not well covered. We realized this would require a different biochemistry to solve. We developed that. We called it our ACE technology. We have patents on that now in the U.S., Europe and in China and ended up resolving that. I think in addition to the sequencing, let’s call it, the laboratory part, in cancer, the question is, can you interpret what you’re seeing? And for us, sure, many people can look at the classic cancer genes, the eGFR and KRAS and so forth that people have looked at for 30 years. But since around 2014, when immunooncology really started to win with the FDA and now has been – become such a large category, we think it’s really important to understand neoantigens because that’s the underlying mechanism of action of the immunooncology drugs. And in order to be able to do that, it’s not just a sequencing problem, but it’s a data interpretation problem. And so this was the reason we spent over 4 years developing our SHERPA technology that I described. And this involved genetically engineering human cell lines, growing them up, looking at the peptides with high-end mass spectrometer, machine learning algorithms. So we said nothing to too is just the sequencing part. And now that we have that kind of a capability, we can look at the genetic variants that we would see out of a tumor, it might be that in an individual tumor, maybe only 1% of the mutations actually can elicit an immune response. And unless you can really say, well, which ones do you think are the 1%? The sequencing itself is perhaps not nearly as useful as it could be. And so the effort that we’ve put in over a period of time to have this proprietary capability to rank the neoantigens, we think, is a huge differentiator, and it goes way beyond the sequencing. So Exact Sciences is a good company, and I understand they are in a number of other areas that really don’t directly compete with what we do. But I think that the technology they have there, I think, is really quite different from the NeXT Platform.
