3. neural tube defect(English)

   • including spina bifida and anencephaly, are severe birth defects of the central nervous system that originate during embryonic development when the neural tube fails to close completely. They are multifactorial, with contributions from both genetic and environmental factors. The genetic basis is not yet well understood, but several nongenetic risk factors have been identified as have possibilities for prevention by maternal folic acid supplementation. Mechanisms underlying neural tube closure and defects may be informed by experimental models, which have revealed numerous genes whose abnormal function provided details of critical cellular and morphological events, essential for closure. Such models also provide an opportunity to investigate potential risk factors and to develop novel preventive therapies
