Red List (low evidence)

Although this is an establised pharmacogenetic phenomenon (haematopoetic toxicity with standard does of antineoplastic drugs 6MP, 6TG or immunosuppression with Azathioprine), this is not green as not considered a phenotype that will present via metabolic clinic and will only manifest with use of certain treatments
