摘要 目的探讨无创产前基因检测在性染色体非整倍体(sex chromosomal aneuploidies,SCA)产前检查中的临床应用。方法对3362名传统产前筛查高中危孕妇及高龄孕妇等采集外周血,抽提胎儿游离DNA,在Hiseq2000上应用大规模并行技术进行测序。对测序高危的孕妇进行侵入性产前诊断。结果在3362份样本中筛查出性染色体异常10例,筛查的阳性率为0.30%。2例无法追踪,其余8例的产前诊断结果:4例XO高危中3例确诊为嵌合体(分别为X、XXX及dup(Y)(q12q11.1)×2的嵌合体)和1例诊断为正常核型;3例XXY高危中2例被确诊和1例诊断为正常核型;1例XXX被确诊。无创产前基因检测SCA的准确率为6/8(75%)(若排除2例无创产前基因检测结果和胎儿嵌合体核型不一致的样本,准确率为50%)。羊水中胎儿性染色体数目异常的检出率在无创产前基因检测开展前后有明显差异(P〈0.05)。结论通过孕妇血浆无创产前基因检测筛查胎儿SCA是可行的,但需进一步确诊。
