    ### Response:
    What are the signs and symptoms of Cohen syndrome? The signs and symptoms of Cohen syndrome may vary greatly from person to person. Some studies have suggested that a large number of people with Cohen syndrome have similar facial features regardless of ethnic background, including thick hair and eyebrows, long eyelashes, wave-shaped palpebral fissures, broad nasal tip, smooth or shortened philtrum, and hypotonic appearance.
