Encephalocele is a neural tube defect characterized by sac-like protrusions of the brain and the membranes that cover it through openings in the skull. These defects are caused by failure of the neural tube to close completely during fetal development.

The syndrome is caused by mutations in any of several genes that affect the division and migration of neural crest cells during embryonic development (though some of the genes involved also affect the neural tube). [5] Neural crest cells are stem cells left over after the closing of the neural tube that go on to form diverse non-CNS cells in ...
Neural tube defects (NTDs) are a group of birth defects in which an opening in the spine or cranium remains from early in human development. In the third week of pregnancy called gastrulation , specialized cells on the dorsal side of the embryo begin to change shape and form the neural tube .
Records do not indicate the cause of death. Samuel Mercedes, infant. A neural tube defect was not diagnosed and the baby suffered severe birth defects, according to 1994 court documents.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Leading cause of death (2016) (world) The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths.
Rachischisis is a neural tube defect characterised by a complete or severe defect in the spine. The defect can be located anywhere from the cervical region to the sacrum, or through the entire length of the spine. Typical defects are clefts or splits that open the spine to the exterior environment.
