摘要
目的:总结拷贝数变异测序(copy number variant sequencing,CNV‐seq)对检测胎儿染色体及巨细胞病毒载量的应用价值。方法:分析CNV‐seq检测胎儿染色体及巨细胞病毒载量的3例巨细胞病毒载量阳性患者的临床基础资料、相关实验室检查、治疗过程及转归并文献复习。结果:3例病例中患者羊水巨细胞病毒载量均小于105 Copies/mL,且其孕期临床表现、产后随访均未见明显神经系统异常。文献复习未见有关CNV‐seq技术应用于巨细胞病毒感染的检测,仅有对已确诊患者进行CMV‐DNA的基因组分析的文献报道。结论:CNV‐seq可用于巨细胞病毒载量的检测,其病毒载量对胎儿的结局可能具有一定程度的预判价值。CNV‐seq可同时检测胎儿染色体及病原微生物,对于出生缺陷防控有着重要意义。
Objective:To summarize the application value of copy number variant sequencing(CNV‐seq)in the detection of fetal chromosome and cytomegalovirus load.Methods:The study analyzed the clinical basic data,relevant laboratory tests,treatment process,and outcomes of three patients with positive cytomegalovirus load detected by CNV‐seq for fetal chromosomes and cytomegalovirus load,and literature review was done simutaneoubly.Results:In all three cases,the amniotic fluid cytomegalovirus load was less than 105 Copies/ml,and there were no significant neurological abnormalities observed during pregnancy or postpartum follow‐up.There is no literature review on the application of CNV‐seq technology in the detection of cytomegalovirus infection,only literature reports on genome analysis of CMV‐DNA in confirmed patients were available.Conclusion:CNV‐seq can be used to detect cytomegalovirus load,which may have a certain degree of predictive value for fetal outcome.CNV‐seq can si‐multaneously detect fetal chromosomes and pathogenic microorganisms,which is of great significance for the prevention and con‐trol of birth defects.
