Summary
Studies how genetic variants alter drug response and side effects.
In depth
Variants in CYP enzymes (CYP2D6, CYP2C9) influence drug metabolism; HLA-B*5701 predicts hypersensitivity to abacavir. Testing guides dosing of warfarin and codeine.
Poor, intermediate, normal and ultra-rapid metaboliser categories result from CYP variants. Testing before prescribing avoids toxicity or lack of effect.
Remember: ethnicity influences allele frequencies, but genotype, not race, is the relevant factor.
Frequently asked questions
What is Pharmacogenomics?
Studies how genetic variants alter drug response and side effects.
Which area of biology covers Pharmacogenomics, and how advanced is it?
Pharmacogenomics is one of the 56 topics in Biotechnology & Genomics. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Gene Drives, Machine Learning in Biology, DNA Fingerprinting.
Can you give an example of Pharmacogenomics?
Some people are ultra-rapid codeine metabolisers, risking overdose.
What should I learn before Pharmacogenomics?
Work through the Beginner topics in Biotechnology & Genomics first, such as Biotechnology, Genetic Engineering, Selective Breeding, then return to Pharmacogenomics. Advanced topics assume the Intermediate vocabulary.
What topics are related to Pharmacogenomics?
The closest topics to Pharmacogenomics are Gene Drives, Machine Learning in Biology, DNA Fingerprinting, GMOs. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Pharmacogenomics?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Pharmacogenomics. To practise the whole of Biotechnology & Genomics, use the Biotechnology & Genomics quiz.
How is Pharmacogenomics different from Gene Drives?
Pharmacogenomics: Studies how genetic variants alter drug response and side effects. Gene Drives: Genetic elements that bias inheritance to spread through a population, proposed to control disease vectors. Read both side by side and note what each one explains.
How should I study Pharmacogenomics step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Gene Drives and explain the difference aloud. Finally, take the Biotechnology & Genomics quiz and come back to this page for any question you miss.
