Our sample comprised 9,531 unrelated individuals of European ancestry with genotype and phenotype data and a diagnosis of depression. Most participants (N = 3,869, 40.6%) had CYP2C19 alleles that would be interpreted as CYP2C19 normal metabolisers. As expected, poor (N = 199, 2.1%) and ultra-rapid … See more We first assessed whether CYP2C19 metaboliser status was associated with differential efficacy across any of the SSRIs under study. Table 2 shows the distribution of self … See more Finally, we tested whether metaboliser status was associated with medication adverse side effects. To reduce multiple testing burden, we focused on reporting any side effect (Table 3). Compared to normal, intermediate … See more We then tested whether CYP2C19 metaboliser status were associated with treatment tolerability. Within participants with genetic and tolerability data, 1885 (45%) 1188 (37%) … See more We performed a power analysis based on simulations (see methods).

Masking: None (Open Label) Primary Purpose: Other: Official Title: Impact of Genetic Polymorphism on Drug Interactions Involving CYP2C19: Risk of Phenoconversion in Healthy CYP2C19 Fast, Normal and Intermediate … Cytochrome P450 2C19 (abbreviated CYP2C19) is an enzyme protein. It is a member of the CYP2C subfamily of the cytochrome P450 mixed-function oxidase system. This subfamily includes enzymes that catalyze metabolism of xenobiotics, including some proton pump inhibitors and antiepileptic drugs. In humans, it is the CYP2C19 gene that encodes the CYP2C19 protein. CYP2C1… the globe jobs
