Figure 1

Shows observed and expected frequencies (%) of phenotypes for the three genes (A, CYP2D6; B, CYP2C19; C, CYP2C9) investigated for 18 study participants of European descent. “Observed” indicates the % of poor (PM), intermediate (IM), rapid (RM), and ultra-rapid (UM) metabolizers in our cohort. “Expected” indicates the corresponding frequencies reported in a recent report of over 5,000 unselected patients in a comparable Oceania population. * Indicates significantly different (P < 0.05) using chi-squared analysis. As shown in Figure 1(B) , for CYP2C19, we did not encounter any European PMs from a total of 18 European cases. We did observe a CYP2C19 PM in one out of four Māori study participants ( Table 1 ).
