Disorganisation: a case with popliteal pterygia and placental-skin appendages.

We report a girl with congenital anomalies which include amniotic rings and scars, cleft lip and palate, thumb abnormalities, hexadactyly of feet, severe flexion deformities of legs and unusual finger-like appendages which were attached to the placenta. We suggest this patient represents another example of human homologue for the mouse mutant disorganisation (Ds).
