    - rare anomaly
    - absence of digit, w/ cleft hand ("lobster claw" hand);
    - phalanges of middle finger, & sometimes corresponding metacarpal, are absent, & cleft in the plane of the missing digit & metacarpal 
            separates the hand into medial and lateral portions;
    - digits on either side of cleft may exhibit various degrees of fusion;
    - in many cases, is associated w/ tibial hemimelia
