Marden-Walker syndrome (MWS) is a malformation syndrome characterized by multiple joint contractures (arthrogryposis), a mask-like face with blepharophimosis, micrognathia, high-arched or cleft palate, low-set ears, decreased muscular bulk, kyphoscoliosis and arachnodactyly.

Cleft palate is a developmental defect of the palate resulting from a failure of fusion of the palatine processes and manifesting as a separation of the roof of the mouth (soft and hard palate).
