There's a human gene called.... The Sonic Hedgehog gene. http://en.wikipedia.org/wiki/Sonic_hedgehog Guess there's a bit of Sega in all of us!
Followed quickly by greatest name for a (possibly) genetic disorder: 'Jumping Frenchmen of Maine' "Jumping Frenchmen" is a disorder characterized by an unusually extreme startle reaction. The startle reaction is a natural response to an unexpected noise or sight. This disorder was first identified during the late nineteenth century in Maine and the Canadian province of Quebec. Lumberjacks of French Canadian descent were originally associated with this phenomenon but it has since been observed in other societies in many parts of the world as well. "Jumping Frenchmen" is suspected to be a genetic disorder and/or an extreme conditioned response to a particular situation possibly influenced by cultural factors. Symptoms tend to improve with age. http://www.cigna.com/healthinfo/nord380.html
It is a human gene. It says - Mutations in the human sonic hedgehog gene, SHH (and present in many other mammals too.) It is called a 'hedgehog' gene because "The hh loss of function mutant phenotype causes the embryos to be covered with denticles (small pointy projections), much like a hedgehog.
