The purpose of this study is to determine whether couples receiving genetic counselling because of a child with a neural tube defect (NTD) are a selected group and therefore not representative of the general population with respect to sib risks for NTDs.

✦ Synopsis
Data for the risk of neural tube defects in sibs of affected children are needed for genetic counselling, for decision on prenatal studies, and for planning of preventive measures. Data have been reported from various populations but were lacking for Germany. This study presents data on the siblings of 240 index patients in the Western part of the Federal Republic of Germany. The prevalence among sibs of affected individuals was found to be 2.6%. This figure agrees well with reports from other countries in Continental Europe and the United States, and fits the expectation of lower recurrence risks in low incidence populations.

A number of studies have demonstrated that the common polymorphism 677C→T in the gene encoding 5, 10-methylenetetrahydrofolate reductase (MTHFR) leads to a thermolabile variant with decreased enzyme activity and to mildly elevated plasma homocysteine. 677TT homozygosity was shown to be more frequent
In the County of Fyn, Denmark, which is a well-delimited region comprising a 10% representative sample of the total population, ten complete one year cohorts of newborn were scrutinized for neural tube defects (NTD). Among 66,000 births, 71 cases with NTD were observed. The total prevalence at birth
