Dysmorphic features are abnormal types of body structures which are normally present from birth, though they might not be recognized right away. These types of features, sometimes called mutations, can be as simple as larger eyes or bent fingers. Conditions like Down syndrome are commonly found with dysmorphic features, such as folds of skin over the medial eyes.
Many of these types of features can be genetic, passed from parent to child, or they can be a type of ethnic identifier. One such example of an ethnic identifier is the different eye appearances between Asians and other races around the world. These types of features can be a visual clue to doctors or parents that there might be other disorders going on and not just a physical mutation.
