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.

Dental malocclusion refers to an abnormality of the occlusion, or alignment, of the teeth and the way the upper and lower teeth fit together, resulting in overcrowding of teeth or in abnormal bite patterns.
