To explore the genetic basis for a fetus with lissencephaly.
Genomic DNA was extracted from amniotic fluid sample and subjected to copy number variation (CNV) analysis.
The fetus was found to harbor a heterozygous 5.2 Mb deletion at 17p13.3p13.2, which encompassed the whole critical region of Miller-Dieker syndrome (MDS) (chr17: 1-2 588 909).
The fetus was diagnosed with MDS. Deletion of the PAFAH1B1 gene may account for the lissencephaly found in the fetus.
探讨无脑回胎儿的遗传基础。
从羊水样本中提取基因组DNA，并进行拷贝数变异（CNV）分析。
发现该胎儿在17p13.3p13.2处存在杂合性5.2 Mb缺失，该缺失区域包含米勒-迪克尔综合征（MDS）的整个关键区域（chr17: 1-2 588 909）。
该胎儿被诊断为MDS。PAFAH1B1基因的缺失可能是导致胎儿无脑回的原因。
