The Global Organization that oversees the naming of genes. renamed I think 27 different genes so they would be Excel friendly. They set up guidelines to say you can't name stuff that might be understood in a non obvious way by Excel. It's crazy. As someone from a computer background, you would think, well, why would it matter what it's named? But we've all been bitten by those Excel trying to help you with things that just make it all the more worse.
