How would I tell if I have Klinefelter s syndrome (I am a woman) what signs do I look for? I have been told that I have Marfan s Syndrome, I am really tall, bad teeth, they are crammed in my mouth, I have a bad heart, messed up lungs and am on an asthma inhaler, bad eyesight, was hyper active as a kid, dyslexic with numbers (not with reading), I am thin with small bones, small hands and feet and am tall, my circulatory system is messed up, my feet and hands are always cold, I have a small head and really long neck. I have always had really no interest in sex. I have heard these are signs of both diseases.
