Sonic hedgehog - Wikipedia, the free encyclopedia

Some clinicians and scientists criticise giving genes frivolous or quirky names, calling it inappropriate that patients with "a serious illness or disability are told that they or their child have a mutation in a gene such as Sonic hedgehog."

[Mikhail Gorbachev]

Haha. I remember a topic a while back about a cancer-causing gene called POKEMON.
I'm pretty sure they had to rename it.
