BACKGROUND: Neural tube defects (NTDs), including spina bifida and anencephaly, are
the second most common birth defect with an incidence of 1/1000. Genetic factors are …

The epidemiological investigation of the common open neural tube defects (NTDs),
anencephaly, and spina bifida, has a long history. The most significant finding from these …

BACKGROUND Recognized risk factors for neural tube defects (NTDs) poorly predict
population‐level NTD risk. However, the proportion of NTDs that can be attributed to these …

We previously reported that among neural tube defects (NTDs) with no known causes the
ones that occur alone (singles) have different epidemiologic characteristics from those that …

The worldwide incidence of neural tube defects (NTDs) ranges from 1.0 to 10.0 per 1,000
births with almost equal frequencies between two major categories: anencephaly and spina …

Neural tube defects (NTDs) have a well‐established genetic basis, although no single
genetic factor has been identified as a major risk factor in NTD susceptibility. A large number …

Isolated neural tube defects (NTDs) appear to have different risk factors compared to
nonisolated NTDs. To extend those observations, we explored routinely collected child and …

Abstract Objective Neural tube defects [NTDs] are severe congenital anomalies. The
etiology of NTDs is not fully known, and studies on the potential risk factors of NTDs present …
