I watched a show on National Geographic last night about cannibalism. Researchers turned up specific genes in 2/3rds of a representative sample of people from all over, M/V that protects against prions from eating brains, especially of our own species. About 10% have V/V which they didn't get into and the M/M people do not have those defenses against prions.

These were the letters mentioned on the show, they seem to have slightly different designations in the article.


Here is a link to part of the story.
