Symptoms Associated With Noonan Syndrome

Distinct Facial Features

Noonan syndrome patients typically have a number of distinct facial features, though these can vary slightly from patient to patient. Some of the most common are drooping eyelids, wide-set eyes with pale irises, a large head size, and a broad forehead. Patients may also have facial droopiness, low-set ears, and a short neck with excess skin. As the patient gets older, the skin may become thinner and more transparent, and their facial features may sharpen. Some patients with Noonan syndrome also have distinctive features in the nose and mouth. The nose may be short and broad, appearing pushed in at the top of the nasal bridge and having a bulbous tip. The patient's upper lip may have wider than usual peaks, and there is often a very deep fold between the edge of the nose and corner of the mouth. The patient's jaw may be quite small, and they might have a highly arched palate. If the patient desires, surgical interventions can be used to alter some of the facial features associated with Noonan syndrome.
