A very rare genetic disorder characterized by the following congenital malformations: hydrocephalus (due to Dandy-Walker anomaly), cleft palate, and severe joint contractures. Finding site True Fourth ventricle structure Inferred relationship Some 7
A rare malformation disorder characterized by sagittal craniosynostosis, Dandy-Walker malformation, hydrocephalus, craniofacial dysmorphism (including dolichocephaly, hypertelorism, micrognathia, positional ear deformity) and variable developmental delay. Finding site False Fourth ventricle structure Inferred relationship Some 6
A rare multiple congenital anomalies/dysmorphic syndrome characterized by severe intellectual deficit, Dandy-Walker malformation, macrocephaly, severe myopia, brachytelephalangy with short and broad fingernails, and dysmorphic facial features (such as thick eyebrows, synophrys, epicanthal folds, low-set ears, short philtrum, and high-arched palate). Additional reported manifestations include seizures and skeletal and genital anomalies, among others. There have been no further descriptions in the literature since 1989.

Dandy-Walker syndrome Finding site True Fourth ventricle structure Inferred relationship Some 2
A syndromic disorder with, as a major feature, the association between Dandy-Walker malformation and postaxial polydactyly. The Dandy-Walker malformation has a variable expression and is characterized by a posterior fossa cyst communicating with the fourth ventricle, the partial or complete absence of the cerebellar vermis, and facultative hydrocephalus. Postaxial polydactyly includes tetramelic postaxial polydactyly of hands and feet with possible enlargement of the fifth metacarpal and metatarsal bones, as well as bifid fifth metacarpals. Finding site False Fourth ventricle structure Inferred relationship Some 4
A rare central nervous system malformation characterized by severe intellectual deficit, early hypotonia with progression to spasticity and contractures, choreoathetosis, seizures, dysmorphic face (long face with prominent forehead), and brain imaging abnormalities such as Dandy-Walker malformation, and iron deposition.

A rare, syndromic intellectual disability characterized by macrocephaly, short stature, intellectual disability, variable degree of spastic paraplegia, central nervous system malformations (hydrocephalus, Dandy-Walker malformation), and dysmorphic features, such as high and broad forehead, midface hypoplasia, and small and broad hands and feet. There have been no further descriptions in the literature since 1993. Finding site True Fourth ventricle structure Inferred relationship Some 5
