Born as conjoined – and therefore genetically identical – twin sisters, Lori Lynn and Dori Schappell (USA, b. 18 September 1961) became the First same-sex conjoined twins to identify as different genders when, in 2007, Dori declared that he was transgender, identifying himself as a male named George.

The craniopagus twins have separate bodies but partially fused skulls, and share bone, vital blood vessels and 30% of their brain (the frontal lobe and the parietal lobe).
