Bimm 118 Worksheet #1 TA: John Diep 1. Define pharmacogenetics and provide two examples that demonstrate this concept. Explain examples. Pharmacogenetics examines the variations in drug response that are influenced by genetic factors. Ex.1 Asian Flush Asian flush is caused by a toxic accumulation of acetalaldehyde due to mutation(s) in an enzyme involved in EtOH metabolism. 1. Alcohol Dehydrogenase mutation – more active; rapid conversion of EtOH to acetaldehyde 2. Acetalaldehyde Dehydrogenase mutation – less active; slow conversion of acetaldehyde to acetic acid Ex. 2 Codeine Resistance Codeine is a prodrug that must be metabolized into morphine, the active drug. Some people have a less active form of the P450 enzyme that is required to complete this step, so the codeine remains unchanged and no therapeutic effects are observed. 2. Provide an example of a drug or drug class that is both prophylactic and palliative.
