PharmGKB contains no dosing guidelines for this . To report known genotype-based dosing guidelines, or if you are interested in developing guidelines, click here.

PharmGKB annotates drug labels containing pharmacogenetic information approved by the US Food and Drug Administration (FDA), European Medicines Agency (EMA) and the Pharmaceuticals and Medical Devices Agency, Japan (PMDA). PharmGKB annotations provide a brief summary of the PGx in the label, an excerpt from the label and a downloadable highlighted label PDF file. A list of genes and phenotypes found within the label is mapped to label section headers and listed at the end of each annotation. PharmGKB also attempts to interpret the level of action implied in each label with the "PGx Level" tag.


  • FDA Information is gathered from the FDA's "Table of Pharmacogenomic Biomarkers in Drug Labels" and from FDA-approved labels brought to our attention. Please note that drugs may be removed from or added to the FDA's Table without our knowledge. We periodically check the Table for changes and update PharmGKB accordingly. Drugs listed on the Table to our knowledge are tagged with the Biomarker icon. A drug label that has been removed from the Table will not have the Biomarker icon but will continue to have an annotation on PharmGKB stating the label has been removed from the FDA's Table. We acquire label PDF files from DailyMed.
  • EMA European Public Assessment Reports (EPARs) that contain PGx information were identified from [Article:24433361] and also by searching for drugs for which we have PGx-containing FDA drug labels.

We welcome any information regarding drug labels containing PGx information approved by the FDA, EMA, PMDA or other Medicine Agencies around the world - please contact feedback.

European Medicines Agency (EMA) Label for eltrombopag and F5, SERPINC1

Actionable PGx


The EMA European Public Assessment Report (EPAR) highlights that caution should be taken when administering eltrombopag in patients with known risk factors for thromboembolism, including Factor V Leiden (F5 gene) and ATIII deficiency (SERPINC1 gene).

Pharmaceuticals and Medical Devices Agency, Japan (PMDA) Label for eltrombopag and SERPINC1

Actionable PGx


The PMDA package insert for eltrombopag notes that caution should be taken when administering the drug to patients with risk factors for thromboembolism, including antithrombin III (AT III; SERPINC1 gene) deficiency and antiphospholipid antibody syndrome, as these patients are at a further increased risk for thromboembolism when receiving eltrombopag.

PharmGKB contains no Clinical Variants that meet the highest level of criteria.

Disclaimer: The PharmGKB's clinical annotations reflect expert consensus based on clinical evidence and peer-reviewed literature available at the time they are written and are intended only to assist clinicians in decision-making and to identify questions for further research. New evidence may have emerged since the time an annotation was submitted to the PharmGKB. The annotations are limited in scope and are not applicable to interventions or diseases that are not specifically identified.

The annotations do not account for individual variations among patients, and cannot be considered inclusive of all proper methods of care or exclusive of other treatments. It remains the responsibility of the health-care provider to determine the best course of treatment for a patient. Adherence to any guideline is voluntary, with the ultimate determination regarding its application to be made solely by the clinician and the patient. PharmGKB assumes no responsibility for any injury or damage to persons or property arising out of or related to any use of the PharmGKB clinical annotations, or for any errors or omissions.

The mRNA boundaries are calculated using the gene's default feature set from NCBI, mapped onto the UCSC Golden Path. PharmGKB sets gene boundaries by expanding the mRNA boundaries by no less than 10,000 bases upstream (5') and 3,000 bases downstream (3') to allow for potential regulatory regions.
