#Polygenic
Our work on the generalizability of polygenic scores (PGS) from the @arbelharpak.bsky.social Lab is now officially out!

We examine the accuracy of PGS predictions at the individual level. We make 3 observations that expose gaps in our understanding of PGS “portability.”

By combining millions of genetic variants into polygenic scores (PGS), researchers can predict educational & mental health outcomes.

In her new blog, PhD student Yujing Lin shows how PGS work through family & environmental contexts, not just biology. 🔗

Quantifying Polygenic scores to determine your risk to diseases and mutations, some arguing they can be cured. Others determining ur value. This is a dangerous line to be drawn...who determines? And the techno-facists are now facing off with religious-nationalists to decide consumer gene editing.

Reproductive autonomy has long been a core ethical principle of genetic counseling. But polygenic screening of embryos for non-medical traits uses the autonomy argument to justify the practice. THhs eugenic practice turns the ethical tables on us.
Justifying Preimplantation Polygenic Embryo Screening: The Autonomy Chickens Come Home To Roost
Autonomy has been a core guiding ethical principle of genetic counselors pretty much since the profession's founding in the early 1970s. There are various definitions of autonomy but on a work-a-day basis in genetic counseling, it is usually conceptualized as the right of patients to make decisions about genetic testing that are educated and without undue external influence or pressure. It relies heavily on information-based consent.

We would like to point out excellent work by Yi Ding, @bpasaniuc.bsky.social et al. which relatedly analyzes attributes of polygenic scores as a function of genetic distance from the GWAS sample.

The NYT has never "fallen" for race science... the science section has been open in its embrace of genetic determinism, sociobiology/evopsych, IQ studies, and polygenic scores for decades. It obviously informs editorial practices being the science "reporting."

Why do some individuals defy their polygenic score?

In the largest study of its kind (402k UKB individuals; 7 continuous traits + 3 diseases), we asked: If your phenotype deviates from common-variant polygenic score prediction, what's driving that difference?

In other words, the current modality using genetics and polygenic risk scoring does not provide any prediction to amyloid accumulation. Hypothesis: DNA Methylation is altering the genetic risk and can be measured by amyloid accumulation.

Excited to see the outcomes 🤞

God has given me the greatest challenge, nay burden, by having me inherit a set of polygenic traits, which causes me to be attracted to men.

God what is it that you want me to learn, perhaps one day even grow to understand about these wholly unserious creatures .... idk man

These genetic signals translated to prediction. Polygenic scores derived from MTAG strongly predicted incident aortic stenosis, with ~3-fold higher risk among individuals in the top 5% of polygenic risk in MGB Biobank and AllofUs.

Nucleus Genomics recently plastered the New York City subway with ads urging prospective parents to “pick your best baby” using their $30,000 polygenic embryo screening service, which they call “IVF+.”

And of course there’s zero problem with the factuality of the claim that “iq is 50% genetic” as opposed to “intelligence is a polygenic trait and there is dispute about what exactly an IQ score measures” which would admittedly be less catchy

If eugenics is of concern, we need a coalition from a wide range of expertise together with engagements towards families seeking reproductive assistance. For instance, just complaining about the technical aspects of polygenic scoring is just too defensive, though looks *scientific*.

«The finding contradicts the general consensus on the polygenic origin of mental disorders. Until now, clinicians have considered that these diseases arise from the interaction of multiple factors, including genetic ones.»

would add to this that any polygenic selection criteria for IQ will inevitably pull through a bunch of linkages and pleiotropies that i would wager heavily are "psychologically suboptimal"

(the real question is "can we get a polygenic score for propensity to respect the autonomy of other humans that's worth a damn?")
