Wolf-Hirschhorn syndrome (WHS) is caused by partial deletion of the short arm of chromosome 4 and is characterized by dysmorphic facies, congenital heart defects, intellectual/developmental disability, and increased risk for congenital diaphragmatic hernia (CDH). In this report, we describe a stillborn girl with WHS and a large CDH. A literature review revealed 15 cases of WHS with CDH, which overlap a 2.3-Mb CDH critical region. We applied a machine-learning algorithm that integrates large-scale genomic knowledge to genes within the 4p16.3 CDH critical region and identified , , , , , , , and as genes whose haploinsufficiency may contribute to the development of CDH.
沃尔夫-赫希霍恩综合征(WHS)由4号染色体短臂部分缺失引起,其特征为面部畸形、先天性心脏缺陷、智力/发育障碍以及先天性膈疝(CDH)风险增加。在本报告中,我们描述了一名患有WHS和巨大CDH的死产女婴。文献综述显示有15例WHS合并CDH的病例,这些病例重叠于一个2.3兆碱基的CDH关键区域。我们应用了一种机器学习算法,该算法将大规模基因组知识整合到4p16.3 CDH关键区域内的基因中,并确定了 、 、 、 、 、 、 和 为单倍剂量不足可能导致CDH发生的基因。
