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), the Pharmaceuticals and Medical Devices Agency, Japan (PMDA), and Health Canada (Santé Canada) (HCSC). 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.

See the legend for more information about drug label sources and PGx Levels.

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

FDA Label for warfarin and CYP2C9, PROC, PROS1, VKORC1

Actionable PGx

Summary

Warfarin (Coumadin) is an anticoagulant used as a prophylaxis and to treat venous thrombosis, pulmonary embolism, thromboembolic complications from atrial fibrillationa and cardiac valve replacement, and to reduce the recurrence of myocardial infarction. The FDA recommends genetic testing for CYP2C9 and VKORC1 variants prior to initiating treatment with warfarin. The drug label notes that deficiency in protein C (PROC) or protein S (PROS1) have been associated with tissue necrosis following warfarin administration.

Health Canada Santé Canada (HCSC) Label for ethinyl estradiol, norelgestromin and F2, F5, MTHFR, PROC, PROS1, SERPINC1

Actionable PGx

Summary

The product monograph for norelgestromin and ethinyl estradiol (EVRA) states that the drug is contraindicated in women with Factor V Leiden mutation, antithrombin-III-deficiency, protein C deficiency, protein S deficiency, hyperhomocysteinaemia due to mutations in the MTHFR gene and prothrombin mutation G20210A (among other contraindications), due to the risk for arterial or venous thrombosis.

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 table below contains information about pharmacogenomic variants on PharmGKB. Please follow the link in the "Variant" column for more information about a particular variant. Each link in the "Variant" column leads to the corresponding PharmGKB Variant Page. The Variant Page contains summary data, including PharmGKB manually curated information about variant-drug pairs based on individual PubMed publications. The PMIDs for these PubMed publications can be found on the Variant Page.

The tags in the first column of the table indicate what type of information can be found on the corresponding Variant Page on the appropriate tab.

Visualization

UCSC has a Genome Browser that you can use to view PharmGKB annotations for this gene in context with many other sources of information.

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.
