After one baby with a neural tube defect the recurrence was 2.3%. Of the 15 pregnancies of women who had two previous babies with neural tube defects, there were three further recurrences. These findings show that the Hungarian recurrence risk of isolated neural tube defects has not changed with a declining birth prevalence, and that the rate in genetic counselling clinic patients is the same as in a previous population based epidemiological study.<\/jats:p>","DOI":"10.1136\/jmg.21.6.413","type":"journal-article","created":{"date-parts":[[2008,11,10]],"date-time":"2008-11-10T15:09:16Z","timestamp":1226329756000},"page":"413-416","source":"Crossref","is-referenced-by-count":23,"title":["Recurrence risk after neural tube defects in a genetic counselling clinic."],"prefix":"10.1136","volume":"21","author":[{"given":"A","family":"Czeizel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"M\u00e9tneki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1984,12,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"429","DOI":"10.1136\/bmj.287.6389.429","article-title":"Spina bifida and anencephaly","volume":"287","author":"Czeizel, A.","year":"1983","unstructured":"Czeizel A.
