Ablepharon Macrostomia Syndrome is an extremely rare inherited genetic disorder that is characterized by different physical abnormalities that affect the head and facial areas, skin, fingers, and the genitalia. The people affected by AMS may also have malformations of the nipples and the abdominal wall. Younger individuals might experience language difficulties, and in some instances mental retardation is known.
