At Salon, an article entitled “The college class that could reveal your real father” by Katya Cengel discusses a course at Stanford called “Genetics 210.” The class uses [entirely optional] 23andme testing to explore the many issues associated with genetic testing. Although the class is offered to both graduate and undergraduate students, the class is filled with mostly graduate students.
All students go through the informed consent process carefully, and have access to a genetic counselor and a psychiatrist (although according to the report not a single student has contacted the psychiatrist in the four semesters the course has been offered, and only two have contacted the genetic counselor).
The most interesting aspect of the article, to me, was the complication that identical twins pose to genetic testing. Epigenetic differences aside (which are currently NOT tested), a genetic test for one will directly apply to the other. So what happens when one twin wants to know and the other doesn’t?
