Abnormalities can also be seen in the hands and fingers, as infants with AMS will also have webbed fingers with limited ability to flex and extend the fingers. Infants with AMS will also display small, rudimentary ears that are atypically low-set on the skull. Absence of the zygomatic bone is also possible. Skin may be dry and coarse, excessively wrinkled around the face and loose around the hands yet tight around the finger joints, leading to diminished use of the fingers.
