CV panels have no statin tests?
• All current statin tests require ABN
3A4, 3A5, 2C9, SLCO1B1
• All orderable as single genes at the top of the
req form
Clopidogrel guidelines update 2013
Deepening the evidence base
• Updated literature review
• New section on CYP2C19 sequencing and novel variants. This includes the novel *4B
misclassification issue PGXL addresses in our recent abstract accepted to AMP 2013.
• New section on novel candidate genes.
• New section on who could be considered for CYP2C19 genotyping. Re-focus
recommendations on patients with acute coronary syndromes undergoing PCI.
• Updated data linking CYP2C19 genotype to phenotype.
• Still no recommendations to increase dose in IMs. Discussion about how doubling
the dose is not always enough in IMs and may need to be higher than 150mg/day,
but no complete data for that yet
