Farewell Wake Island! You guys really shared so many amazing stories, authors, music, film. Truly mind opening during the pandemic.

We hope it's easy to use with tutorials for UKB (pgsc-calc.readthedocs.io/en/v3-alpha....) & All of Us (pgsc-calc.readthedocs.io/en/v3-alpha.... )! But feel free to contact us on Github: github.com/PGScatalog/p...!
With that, happy holidays from the PGS Catalog team! 🎁 🎄

The new alpha only implements PGS scoring at the moment, but the roadmap will reimplement our existing genetic ancestry tools! Lot's of under-the-hood optimisation using python (zarr, dash), and it only takes VCF or BGEN input atm. github.com/PGScatalog/p...

Stay tuned here for upcoming updates to pgsc_calc (github.com/PGScatalog/p...), our tool for reproducible PGS calculation. Our next version aims to increase the scalability to WGS data in cloud trusted research environments (e.g. All of Us).

On a personal note, it's great to have the first preprint out from my first PhD student! bsky.app/profile/clai...
I passed my PhD viva! 🎉 Thank you to everyone who has been a part of this incredible journey, especially my supervisors @iamslambert.bsky.social, Angela Wood, and @mikeinouye.bsky.social 😄

There's much more in the preprint - a great team effort from @clairecoffey.bsky.social @sritchie73.bsky.social, Lisa Pennells, Angela Wood & @mikeinouye.bsky.social all from @cambridge-ceu.bsky.social!

Clinical statements (AHA, ESC) have suggested that PRS may be most useful as a risk-enhancing factor for those at intermediate risk. We used PRS to reclassify individuals at intermediate risk by QRISK3 and showed improved sensitivity and fairness benefits (particularly for age & sex).

We evaluated PRS in two contexts, as a standalone risk predictor and as a risk-enhancing factor. Given the known performance differences across ancestries, we were surprised to find that the fairness of PRS predictions across ethnicities was equal to or lower other CVD risk factors when used alone.
