similar scenario for height. even though the common genetics is "saturated" the height range one person could be based on their PRS is very wide. (which is of course a separate argument compared to using PRS to stratify people)

nice summary thanks Andrea. I wonder if this challenge will become easier in a few years if and when clinicians inform a young adult patient they would like to "do" their genetics at the same time as their first blood pressure/FEV/LDL-cholesterol etc test.

Does it even make sense to compare PGS to proteomic risk scores though ? one is a once in a lifetime assay that costs about $40. the other....is not. The most relevant comparison for proteomic scores is likely to be routine biochemistry ?

We probably should be more upfront with the mechanism and research argument. If large % of population are sequenced we have a "human laboratory" regardless of the personalised/stratified medicine argument.

Preventing premature deaths through polygenic risk scores Background Polygenic risk scores (PRS) have demonstrated predictive validity across a range of cohorts and diseases, but quantifying their clinical utility remains a challenge. As PRS can be derived f...

this is a decent summary www.medrxiv.org/content/10.1... I am not sure but i think some of the reticence about PRS is that we are used to only thinking about one condition at a time, but for Β£40 one off test, PRS make a small difference across multiple conditions for most people.

Exciting, but wish the hype was dialled back. "This will enable identification & intervention for individuals at high risk of developing common diseases" probably better as "cheap once in lifetime test will nudge many people over & under certain thresholds for interventions.

timing does seem weird, & hyperbole dialled up to 11, but i read it as referring to common as well as rare diseases, which are mainly adult-onset but not all, notably 50% of Type 1 diabetes. Did the CPM discussions include implications for common later onset disease ?

I have just heard from a US visitor from San Diego. She discussed PhD students in her lab. US citizens of chinese and african ancestry. One a military veteran. Both have received knocks on the door with officials asking them for their birth certificates.

I think it’s patients presenting either to clinical genetics services with severe rare conditions or being part of common disease cohorts and Biobanks. WES and WGS in 100,000s starting to plus the gap but only just getting going
