Abstract：
Four patients with the fragile X syndrome including 3 males and one woman, were evaluated for cardiological abnormalities. One patient had an obvious murmur. All 4 were shown to have mitral valve prolapse by echocardiography. Two male patients also demonstrated mild dilatation of the ascending aorta. We recommend thorough cardiological evaluations of all fragile X patients.
