A team of representatives from the Wellcome Trust Centre for Mitochondrial Research ran a stall at the Great North Children Hospital’s 5th Birthday party where patients, carers and staff could play fairground style games based around mitochondrial genetics. The bean bag respiratory chain game proved popular with patients, with celebrity chefs and the odd storm trooper also taking part. It was a great day thoroughly enjoyed by all who attended as well as the Wellcome Trust Centre for Mitochondrial Research staff.
