Patient's own account: I'm a 20-year-old guy, working as a driver and I went to the clinic for my routine checkup. I have myopia, so I wear glasses and I don't take any other medications. My vitals were normal. I also did a physical exam, and I was told that I have long legs, arms, and fingers. They also told me that my face is quite narrow, with down-slanted eyes and a small jaw. My lungs were fine and my tummy too. I have been diagnosed with Marfan syndrome and I haven't been skipping any medical appointments since.
