A key challenge in human genetics is the discovery of modifiable causal risk factors for complex traits and diseases. Mendelian randomisation (MR) using molecular traits as exposures is a particula...

While sffdr is FDR-based, we calculate p values so GWAS practioners work with familiar quantities. Want to give it a go? Download the R package from . /ends.

sffdr power gain is study dependent, but was equivalent to 60% increase in sample size in a large study of obesity-related traits, and raised number of discoveries from 2 to 10 in study of rare disease EGPA. Another important point: /2.

With the simpler structure, we can also extend the model to learn prior probabilities for the different hypotheses, possibly conditional on trait-level covariates.

We adapt the coloc approach to the case where a causal variant is known with certainty for one trait, and we want to ask if it is also causal for another. This means we can extend the approach to cases such as loss of function variants.

First time COVID and it's awful. All this time wasted feeling rubbish, not even able to read. Can anyone suggest something good to listen to?.

you have a small set of 20 findings identified with through some testing procedure with estimated FDR < 0.05. You subsequently test ten of these in independent data and confirm the findings. Does that mean the FDR in the other ten is now 0.1?.
