| Outline of Final Research Achievements |
The authors’s goal in this study is to provide the first clinical, radiological and genetic studies of panventriculomegary with a wide foramen of Magendie and large cisterna magna (PaVM) defined by a wide foramen of Magendie and large cisterna magna. Adult patients showed gait disturbance, urinary dysfunction, and cognitive dysfunction. Five infant patients exhibited macrocranium. Genetic analysis revealed a deletion in DNAH14 that encodes a dynein heavy chain protein associated with motile cilia function. Immunohistochemistry localized DNAH14 specifically to choroid plexus epithelial cells and ependymal cells. Panventriculomegaly with a wide formen of Magendie and a large cisterna magna may belong to a subtype of congenital hydrocephalus with familial accumulation, younger age at onset, and symptoms of normal pressure hydrocephalus. In addition, a family with PaVM has a gene mutation associated with dysfunction of motile cilia.
