An impressive paper giving precise estimates of heritability from whole genome data. However, although framed in terms of missing heritability, they only compare their estimates to 'pedigree' estimates from UKB, not twin or Loic's own recent sib estimates, which are often…

We are pleased to announce that our new study explaining the missing heritability of many phenotypes using WGS data from ~347,000 UK Biobank participants has just been published in @Nature. Please check out our manuscript here: nature.com/articles/s4158….

Further progress on closing the “missing heritability” gap “On average … we find that WGS captures approximately 88% of the pedigree-based narrow sense heritability: that is, 20% from rare variants (MAF < 1%) and 68% from common variants (MAF ≥ 1%” nature.com/articles/s4158…

The timeline flip will surprise many, but embryo screening polygenic traits like IQ is going to be a mass-market consumer good extremely quickly, when it springboards on PGT-A. Many bioethicists criticized PGT-P on "accessibility" grounds that already look ridiculous.

Herasight has done it again! Now they've invented a way to take some of the most readily available data from IVF clinics and get accurate polygenic scores from it That means Herasight can help any couple do embryo selection! And they want to prove it with 90% off testing!

Today parents can, for the first time, access polygenic embryo testing for IQ and many diseases through a routine test (PGT-A) done worldwide and in 60% of US IVF cycles. Read on to learn how Herasight’s ImputePGTA algorithm is enabling polygenic testing in IVF to go global. 🧵

Excited to get this preprint out! I wanted to highlight the phasing aspect of our pipeline for embryo reconstruction from PGT-A data, which I found particularly interesting as it required developing new methods to achieve the level of accuracy required for ImputePGTA.

We’re proud of this achievement which has been almost four years in the making. Stay tuned for CogPGT 2.0, which will have more variants and more advanced methodology. Exciting times in genomics!

Today we reveal CogPGT, the world’s most powerful genetic predictor of IQ. We achieve a correlation with IQ of 0.51 (0.45 within-family). Herasight customers can boost the expected IQ of their children by up to 9 points by selecting the embryo with the highest CogPGT score. 🧵

Building on @JonathanAnomaly's thread last week, we find no evidence of negative off-target effects from screening for cognitive ability. In fact, our results highlight diverse and positive pleiotropic effects for SES, mental health, physical health, etc.
