Pharmacogenomics: Introductory Cases

In an effort to expand pharmacogenomics knowledge/education, we are providing introductory cases for use by instructors. We will continue to add more cases over time. Please note that the PGx information should be used in conjunction with other data as a component of overall clinical decision-making. While these cases are strictly PGx-related, we do not want to convey that this is the only information to be considered. These are basic PGx cases intended to introduce students to PGx and evidence-based guidelines from the Clinical Pharmacogenetics Implementation Consortium (CPIC).

Obtaining Instructor Keys

Case instructor keys: As an instructor, email to request the instructor keys for each case-PGx testing report combination. In order to maintain instructor access to the keys, the email must be received from a .edu site, and the instructor must provide a link to their listing as a faculty member of their institution. As an example:

Faculty name: David F. Kisor

Faculty email:

Suggested Directions for Pharmacogenomics Cases

  1. Choose a case by selecting a “Student Recommendation Form”. This form contains a case and fields requesting information that the student provides based on their assigned “PGx testing report”.
  2. Assign a “PGx testing report” to each student. Currently there are 65 reports available. Click on the following if you want to choose a specific "PGx testing report" relative to a given gene and genotype or phenotype: PGx Testing Report By Gene.
  3. Have the students complete the “Student Recommendation Form” relative to their assigned “PGx testing report”. Have the student provide the following information:
    • The PGx testing report number in the "Based on report number:" field
    • The relevant gene or genes in the "Relevant gene(s):" field
    • The diplotype for each gene in the "Patient diplotype:" field
    • The metabolism/function/carrier phenotype(s) in the "Patient phenotype:" field
    • Their recommendation based on the case in the "Recommendation:" field
    • Any additional notes in the "Notes:" field
    • Citation(s) that support their recommendation in the "Recommended based on:" field
    • The source (URL) of the citation in the "Found at:" field
  4. Have the student turn-in the completed “Student Recommendation Form” for grading. The point value or other grading associated with each case are up to the instructor.
  5. Use the received instructor keys that are emailed, after supplying the above information (Directions), to grade the “Student Recommendation Form.”
Note: 9/18/19 The testing results reports were updated to include other testing results, specifically HLA-A*31:01. No other changes were made to the results reports. The "_U" denotes the update.
