A rare multiple congenital anomalies/dysmorphic syndrome characterized by hypoglossia, micrognathia and variable limb abnormalities. Limb defects can involve any limb (usually all four) and the severity may vary from the absence of distal phalanges to total absence of digits or limbs. Synbrachydactyly may also be present. Patients have problems with speech, swallowing and mastication, and they have additional craniofacial anomalies (including telecanthus, lower eyelid defects, broad nose, microstomia, variable clefting or aberrant attachments of tongue, mandibular hypodontia, cleft palate, cranial nerve palsies, and facial asymmetry). Gingival abnormalities are frequently observed. Intelligence and stature are generally normal.
