The recurrence of isolated neural tube defects in a population of women from a genetic counselling clinic was found to be 3.4%. 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.
在一家遗传咨询诊所的女性群体中,孤立性神经管缺陷的复发率为3.4%。在有一个神经管缺陷患儿的女性中,复发率为2.3%。在之前有两个神经管缺陷患儿的15名女性的妊娠中,又有3例复发。这些发现表明,匈牙利孤立性神经管缺陷的复发风险并未随出生患病率的下降而改变,并且遗传咨询诊所患者中的复发率与之前一项基于人群的流行病学研究中的复发率相同。
