Mu Tiezhu, a former member of the national basketball team, has a condition called 'acromegaly' (a disorder that results from excess growth hormone).
Mu was one of the first Chinese giants who appeared in the China men's national basketball team. He was often compared with Sun Mingming, because both of them have acromegaly, and could slam dunk without their feet leaving the ground. Acromegaly is a disorder that results from excess growth hormone (GH) after the growth plates have closed.
