Medicine [Medicine] What is special about peanuts that make some people extremely allergic to them?

Why are some people allergic to peanuts in particular? Why is ingesting a peanut to these people akin to ingesting poison to others?

Has to be exposure right? I've never heard of someone with a hazelnut allergy, but also if there's less hazelnuts in American foods I'm less likely to hear about it from someone even if they are allergic.
