CYP2B6 variants predicting aberrant exon 7-9 splicing, generating the SV9 and λMP1 splice-forms, versus correct exon 7-8 splicing, individually or in an optimum multivariate model.

Difference in PCR cycle time (ΔCt) determined by subtracting the Ct value of the PCR reaction using primers ‘7/8F’ and ‘9R’ from the Ct value of the PCR reaction using primers ‘7/9F’ and ‘9R’ (see Figure 4, primer sequences in table S4).
