摘要:

报告1例胎儿淋巴水肿,其母孕中期行胎儿染色体核型分析及单核苷酸多态性微阵列(single nucleotide polymorphism array,SNP array)检测未见明显异常。孕晚期孕妇自觉胎动减少,超声检查提示宫内死胎,对引产胎儿及其父母进行全外显子组测序(whole exome sequencing,WES),发现胎儿携带CELSR1基因杂合缺失c.5060-1_5069delGCCATGCCTCA,父母WES检测结果显示胎儿父亲同时携带该变异且具有正常表型。考虑CELSR1基因杂合缺失与淋巴水肿具有一定相关性,但其临床表型不完全外显。

Abstract:

We reported a case of fetal lymphedema. The chromosome karyotype analysis of fetus and single nucleotide polymorphism array (SNP array) of the amniotic fluid cells showed no abnormalities in the mid pregnancy. However, the pregnant woman perceived a decrease in fetal movement in the late pregnancy, and ultrasound indicated intrauterine stillbirth. Whole exome sequencing (WES) showed that the fetus carried loss of heterozygosity of CELSR1 gene c.5060-1_ 5069 delGCCATGCCTCA. The WES results also showed that the fetal father also carried the mutation and had a normal phenotype. There is a certain correlation between loss of heterozygosity in the CELSR1 gene and lymphedema, but its clinical phenotype is incomplete penetrance.
