Military Enlistment W/ health issue

Patient: Hi, I have the desire to enlist in the United States Marine Corps once I’m 17.(Currently 15) Unfortunately I have an Outward Barrel Chest on my right side. I do not have any of the breathing problems associated with this. There are no noticeable problems that it gives me other than it’s just simply there. Do you believe that its’ presence will have physical limitations on my body and be cause for rejection by M.E.P.S? Thank you. Any suggestions would be helpful. (I’m Male if it helps)

Symptoms: Outward Barrel Chest
no breathing/noticeable problems
