Excited to share our preprint on PGI portability across ancestries—now on bioRxiv. With co-authors @aysuo.bsky.social, @paturley.bsky.social, @alextisyoung.bsky.social, and @Dan_J_Benjamin. Preprint: doi.org/10.1101/2025... Thread below for details.

Dissecting the Predictive Accuracy of Polygenic Indexes for Behavioral Phenotypes Across Genetic Ancestries
Polygenic indexes (PGIs) trained on samples of European genetic ancestries often lose substantial predictive power when applied to non-European ancestries. While this portability problem is well recog...

Siblings are not always 50% genetically similar! The difference may vary from 40 to 60%! Our preprint uses this difference via sibling regression to estimate "assumption-free heritability" of socio-cognitive traits /1 @eivindy.bsky.social @rafaelahlskog.bsky.social @renemottus.bsky.social

Great work on estimating heritability using sibling relatedness variation (estimated using my software package snipar). Surprisingly low h2 for education and high h2 for IQ (with large SE). Give it a read!
