===Curation of the ''Phenotype'' of patient diplotypes===CPIC has recommended to use the term Phenotype for the metabolization status, transportation function or presence of a particular trait. Currently, this Phenotype is not a independent entity in the PharmGKB API. This means that for a drug that is affected by two genes, the Phenotype is aggregated for the two genes. We suggest to make a phenotype per gene, and make a recommendation for the combination of phenotypes. If more genes are added later, then it may be easier to expand the guideline. Another usecase reason for modelling phenotypes on a per gene basis is if that we want to make a guideline that is not drug-dependent, but rather made for families of drugs for Psychopharmaca or Cancer, and involving very many different genes.

As an example, we see that the phenotype ''Voriconazole CYP2C19:Intermediate Metabolizer'' is either a heterozygote Voriconazole CYP2C19:Increased function/No function or a Voriconazole CYP2C19:No function/Normal function:[[File:WebProtege user interface phen.png|framelessthumb|Anticipating inclusion of CPIC definition A model of phenotypes in the PharmGKB API data, we have modelled the CPIC Phenotype by combining combination of pairs of Functional Statuses]]

As an example, we see that the phenotype ''Voriconazole CYP2C19:Intermediate Metabolizer'' is either a heterozygote Voriconazole CYP2C19:Increased function/No function or a Voriconazole CYP2C19:No function/Normal function. As for the functional status, we suggest that curators start a discussion if definitions of Phenotypes should be changed.
