Your son probably has a condition called Marfan Syndrome. If so, it is likely inherited. He needs to be evaluated at a hospital with experience with this disease. I recommend you hold off on athletic endeavors till he has been screened. Meanwhile, he probably should be treated with Beta-blockers, which has been shown to slow the enlargement down.
I have written about this before as part of information about sudden death in young athletes (one happened just this weekend!):
