@slatestarcodex has written a great article on the burgeoning field of embryo selection, featuring our recently launched company @herasight. Scott has used the technology himself and gives an overview of the field - this is an essential read for anyone curious to learn more.

At @herasight, we wanted to compare our genetic predictors (PGS) to those from @nucleusgenomics. However, in many cases, we couldn’t reconcile plausible performance of their PGSs with customer risk reports we saw — this may have misled customers about their disease risks.

I’ve been working with an IVF startup, @herasight, that has already screened hundreds of embryos. Today we come out of stealth with a paper showing that our predictors for 17 diseases — validated within-family — beat the competition, with improved performance in non-Europeans🧵
