There's a lot of memorizing of what gene does what, or what drug's response is affected by a change in gene XYZ. At least they aren't making us memorize each polymorphism found in every gene.
I found the class interesting. I enjoyed genetics during undergrad and it is nice to see it being put to another use besides nailing criminals.
We've looked at mutations in receptors and how they affect drug response, mutations in metabolizing proteins that can cause increased toxicity to certain drugs, specific transporter protein mutations, a couple of genetic disease states, genetic testing and a few other things.
