Causal heterogeneity of anencephaly and spina bifida has been demonstrated; in rare families the neural tube defect may be caused by a single gene. We report a family in which four cases of anencephaly or spina bifida may represent X-linked inheritance.
无脑儿和脊柱裂的病因异质性已得到证实；在少数家族中，神经管缺陷可能由单个基因引起。我们报告了一个家族，其中四例无脑儿或脊柱裂病例可能呈现X连锁遗传。
