People with this condition are born with split hands and feet. Split hands and split foot refers to a developmental malformation consisting of missing digits (fingers and/or toes), a deep median cleft (cleft down the center of the hand or foot), and fusion of remaining digits. People with this syndrome also have rapid involuntary movements of the eyes, called nystagmus. Abnormalities of the teeth can occur rarely.

There have been very few reported cases of split hand split foot nystagmus to date, however mental and motor development seems to be normal. Although not widely documented, this syndrome may be associated with orodental anomalies such as missing teeth, delayed tooth eruption, and abnormal size and shape of the teeth. We are not aware of other common medical concerns.

In general, the prognosis of children with split hand split foot nystagmus seems to be favorable. The degree of disability caused by the loss of function in the limbs and by the eye problems, is largely determined by the degree of severity of these defects.
