Notes from the interpretation layer.
Clinical genomics, variant interpretation, pharmacogenomics and polygenic risk — written for the people who read the reports and sign them.
CYP2D6: the false normal that arrives looking like a result
A pipeline that does not treat the CYP2D6 locus specifically does not return an error. It returns *1/*1 — a poor metaboliser reported as normal, with no alarm of any kind.
