"Sonic hedgehog is a protein that in humans is encoded by the SHH ("sonic hedgehog") gene."
"A potential inhibitor of the Hedgehog signaling pathway has been found and dubbed 'Robotnikinin', in honor of Sonic the Hedgehog's nemesis, Dr. Ivo "Eggman" Robotnik."
"The gene has already been linked to a condition known as holoprosencephaly, which can result in severe brain, skull and facial defects; motivation for some clinicians and scientists to criticize the name on grounds of it sounding too frivolous. They point to a less humorous situation where patients or parents of patients with a serious disorder are told that they or their child "have a mutation in [their] sonic hedgehog"."
