Seven patients with similar phenotypes of developmental delay and microcephaly were found by whole-exome sequencing to have de novo loss-of-function mutations in POGZ. POGZ is a pogo transposable element-derived protein with a zinc finger cluster. The protein is involved in normal kinetochore assembly and mitotic sister chromatid cohesion and mitotic chromosome segregation. POGZ deficiency may affect mitosis, disrupting brain development and function.
通过全外显子组测序发现，7名患有发育迟缓与小头畸形相似表型的患者在POGZ基因中存在新生功能丧失突变。POGZ是一种具有锌指结构簇的源自pogo转座元件的蛋白质。该蛋白质参与正常的动粒组装、有丝分裂姐妹染色单体黏连以及有丝分裂染色体分离。POGZ缺乏可能影响有丝分裂，扰乱大脑发育和功能。
