Great study comparing genetics of disease susceptibilty vs. disease progression 👉at same sample size more loci identifiable in GWAS of susceptibility vs. progression 👉 genetic architecture of disease susceptibility largely different from that of disease-specific mortality
🚨 New preprint out! We reconstructed parental haplotypes in >440k individuals (UK & Estonian biobanks) to estimate assortative mating directly in the parental generation. This reveals intensified assortment in recent generations. 🔗biorxiv.org/content/10.110…
Today we are launching the best IVF calculator in the world. Based on data from over 500,000 cycles, we’ve modelled the distribution of potential outcomes at each stage of IVF. If you are undergoing or considering IVF, explore our calculator on the Herasight website.🧵

We are excited to share GPN-Star, a cost-effective, biologically grounded genomic language modeling framework that achieves state-of-the-art performance across a wide range of variant effect prediction tasks relevant to human genetics. biorxiv.org/content/10.110… (1/n)
Some have questioned why eye color heritability is only ~45% in this study when we 'know' it is genetically determined. Part of the answer is likely assortative mating/population structure. To see this, consider that blue eyes are determined by a single gene, and blue eyed…

Scoliosis is the most common spinal deformity, but its genetic causes are still unclear. Using AI to measure spinal curves in 57,887 people, we discovered 2 novel genetic risk loci - showing how deep learning can unlock insights into musculoskeletal health medrxiv.org/content/10.110…

The impact of location on a child’s outcomes are small but definite. Here, the authors use the random assignment of military families to different bases to get around selection. A 1 SD better neighborhood for 20 years raises SAT score by 40 points. 1/
@herasight found that many Nucleus polygenic scores used few SNPs, with much lower performance than implied by their reports, potentially misleading customers about disease risk (thread below). Instead of responding to these criticisms, they release more marketing hype.…

about 1 in 500 men have an XXY karyotype, i.e. two X chromosomes. 75% of them are unaware of this. associations include: - 16x odds of infertility - 5x odds of venous thrombosis - several others Interesting study!

The "First Law of Behavioral Genetics" states that all traits are at least partially heritable. But @eawilloughby and her colleagues found an exception to the Law: beliefs about free will and determinism! Beliefs about fatalism and unpredictability had low heritability (in the…
