【摘要】 一例25岁孕妇,产前超声检查发现胎儿小脑蚓部异常,胎儿MRI检查发现脑干"磨牙征",小脑上蚓部仅见少量组织。引产后胎儿MRI检查和尸体解剖发现小脑蚓部发育不良,第二代基因测序技术发现胎儿染色体CC2D2A基因存在c.2728C>T和c.4598T>C的复合杂合突变基因。

【Abstract】 A 25-year-old nulliparity underwent prenatal ultrasonography, and the fetal cerebellar abnormality was suspected. The fetal MRI showed ’ molar tooth sign ’ in midbrain and cerebellar vermis hypoplasia. The fetal cerebellar vermis hypoplasia was confirmed by MRI imaging and autopsy after induced abortion. The next-generation sequencing showed that the fetus had a heterozygous mutation of CC2 D2 A gene( c.2728 C >T and c.4598 T > C), which might be the cause of the disease.
