There was a gene called Pokemon but had to change due to legal action!
Pokemon, formally called Pok, is a gene found by researchers in New York to cause cancer. Many news reports joked about the relation between the popular cartoon and the carcinogen! The brand was being associated with causing cancer.
Because of this, Pokémon USA was not thrilled by the jokes. The Nintendo sub-division threatened to sue the Memorial Sloan-Kettering Cancer Center because of an unflattering relation between their brand and cancer! The researchers eventually gave in to Pokémon USA’s demands and changed the gene’s name to Zbtb7.
