lol yeah I have a hand with a single transverse palmer crease. I was looking around on wikipedia too. Just the other day I was at a hospital in a class and the teacher was talking about how a single crease can be an indication of Down syndrome. Of course, all the students pulled out their hands and looked and when I checked my hand, I though I had heard her wrong but when I showed my friend she was surprised. We got the teacher over and showed her. She was pretty surprised too. Anyway, lol I got a ton of attention that day. Well, anyway yeah, I've got it too. :)
