What are the symptoms of split hand split foot nystagmus?

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.[1] People with this syndrome also have rapid involuntary movements of the eyes, called nystagmus.[2] Abnormalities of the teeth can occur rarely.[3]
