Do you have any interesting genetic traits/abilities?

I find genetics quite interesting, or really just anything interesting in general. I don't personally have anything too rare besides IQ, but I suspect I may have some kind of variation of the DEC2 gene.

However, I do know someone who can shake their eyes and another person who can cry on command.

Do you happen to have anything interesting you?

(also, think this goes without saying, but please don't talk about your third eye or extra limb here)
