In Mid-Ulster, about 1 in 150 people carry a genetic mutation to the AIP gene that leads to an overproduction of growth hormone resulting in acromegaly, also known as gigantism.

"This is probably the highest proportion of giants in the whole world in that little part of Northern Ireland," Marta Korbonits, professor of endocrinology at Barts and the London School of Medicine Queen Mary.
