Improving clinical recognition of Marfan syndrome.

Marfan syndrome is a potentially fatal disorder with cardiovascular, skeletal, and other manifestations that may also be seen in individuals without Marfan syndrome, making diagnosis difficult. Our goals were (1) to examine the ways in which patients have been recognized as having Marfan syndrome, (2) to examine the prevalence of current diagnostic findings, and (3) to determine which physically evident features are most sensitive and specific for referral to confirm a diagnosis of Marfan syndrome.
