A rare genetic multiple congenital anomalies/dysmorphic syndrome characterized by variable developmental delay and intellectual disability, movement disorder or gait abnormalities, and dysmorphic craniofacial features (such as facial asymmetry, broad forehead, posteriorly rotated ears, thick lower lip, micrognathia, or cleft palate).
