Can't comment on the genetics but agree this is a huge "so what?" for clinical practice – we already use patient-specific trends for diagnosis and management and have for decades. The specific examples given in the article (like HCT and CKD) are... amusingly obvious.

Arguably the reason that GWAS for blood traits have ever worked is that we are proxying the individual set point. So yes the clinical discussion is neat. The genetic implications seem nil.

The truth is nobody should care how many protein coding genes there are. The gene is a useful abstraction that loses its utility when defined precisely enough to count.

Does it make sense to still use P<5e-8 as significance threshold in today's GWASs that include more and more rare variants (as the imputation quality continuously improve with large data and better reference panels)?

Challenging when annotating variants, especially for discovery studies. And when looking at different transcripts for each gene, the numbers and sequences change wildly across databases. Many transcripts share only the gene name and not the function: the question mark on encoded proteins is huge

Fascinating paper on individual setpoints for blood count variables. Much better risk estimation when you interpret any given measurement from a person in light of all previous measurements. And I bet it is applicable much more widely to other blood tests. www.nature.com/articles/s41...
