The first time I saw my cardiologists he told me I have characteristics of Marfans, (scoliosis, near-sighted, concave sternum, double-jointed to name a few) but never that I have the syndrome. I am just under 5'7, so not terribly tall, although my dads family is pretty tall, his sister and other women were taller than me, and thin. Looking at old pictures I wonder if anyone had it and just some of the characteristics are passed down? He had heart disease but not valve troubles, and his mother's side (the tall, skinny ones) all died relatively young of other things. Anyhow, I have been diagnosed with connective tissue disorder. I always thought it was cool to be double jointed when I was younger, and still flexible even in my late 30's, although not so cool when I realize it probably contributed to my valve troubles.
