as my cousin was diagnosed with it as she got very long twisted arms and long legs, 6' 1" tall, a very small head and her eyes arent straight (one eye is higher than the other)
her Grandmother died when she was 29 of a bad heart - she had the marfan syndrome
now her niece (my cousins sisters DD) is 8 mths old and may have it too as she got long arms and legs - she was a normal looking size baby when newborn.
