Scientists have discovered the werewolf gene, called hypertrichosis.
Experts know that the extremely rare condition runs in families and in 1995, researchers studied a Mexican family with the disorder. They found the mutation in a section of the X chromosome in the family genes, but it was a man from China that unraveled the mystery.
The gene is called SOX3, and is responsible for playing a role in the growth of hair of the man in China and his family members, and then went to Mexico to find the same gene in the same on the same X chromosome in the second family.
The Guinness Book of World Records and a circus seems to be the only place to find people afflicted with the werewolf gene, which isn’t all that surprising.
