Meningomyelocele is one of the most severe forms of neural tube defects (NTDs) and the most frequent structural birth defect of the central nervous system. We assembled the Spina Bifida Sequencing Consortium to identify causes. Exome and genome sequencing of 715 parent-offspring trios identified six patients with chromosomal 22q11.2 deletions, suggesting a 23-fold increased risk compared with the general population. Furthermore, analysis of a separate 22q11.2 deletion cohort suggested a 12- to 15-fold increased NTD risk of meningomyelocele. The loss of Crkl, one of several neural tube–expressed genes within the minimal deletion interval, was sufficient to replicate NTDs in mice, where both penetrance and expressivity were exacerbated by maternal folate deficiency. Thus, the common 22q11.2 deletion confers substantial meningomyelocele risk, which is partially alleviated by folate supplementation.

常见 22q11.2 缺失介导的脑膜脊髓膨出风险

脑膜脊髓膨出是最严重的神经管缺陷 (NTD) 形式之一，也是中枢神经系统最常见的结构性先天缺陷。我们组建了脊柱裂测序联盟来确定原因。对 715 名亲子三人组的外显子组和基因组测序发现，6 名患者存在染色体 22q11.2 缺失，表明与一般人群相比，风险增加了 23 倍。此外，对单独的 22q11.2 缺失队列的分析表明，脑膜脊髓膨出的 NTD 风险增加了 12 至 15 倍。Crkl是最小缺失间隔内的几个神经管表达基因之一，其缺失足以在小鼠中复制 NTD，而母体叶酸缺乏会加剧外显率和表达能力。因此，常见的 22q11.2 缺失会带来巨大的脑膜脊髓膨出风险，补充叶酸可以部分缓解这种风险。
