Anencephaly is one of the most severe types of neural tube defects (NTDs). The neural tube is the developing structure that becomes the brain, skull and spine. NTDs in general are one of the most common birth defects, occurring in approximately 1 in 1,000 live births in the United States. Anencephaly occurs when the top, or cephalic portion, of the neural tube does not close properly during fetal development. This results in a partial or complete absence of the brain and skull. If carried to term, babies with anencephaly typically die during delivery or shortly thereafter. Currently, there is no cure or treatment for anencephaly and the cause is not known. It is strongly suspected that anencephaly and other NTDs are due to a combination of multiple genetic and environmental factors.


The Duke Molecular Physiology Institute (DMPI), formerly the Duke Center for Human Genetics, is currently conducting a genetic study called "The Hereditary Basis of Neural Tube Defects" to determine the causes of anencephaly and other NTDs. By studying families with anencephaly and other NTDs, we hope to identify the genes that contribute to the development of the neural tube. We hope this research will eventually lead to more accurate genetic counseling and risk assessment, improved treatments, better prevention methods, and possibly, a cure.


This study is no longer enrolling new participants. Research continues utilizing the samples and data collected from the large number of previously enrolled participants. Thank you to all the families who have participated over the years. Research toward a better understanding of the causes of neural tube defects would not be possible without your help.
