摘要 目的探讨政府投入开展无创产前基因检测(NIPT)在胎儿染色体非整倍体疾病诊断中的应用性研究。方法由政府财政投入专项资金,充分发挥产前无创产前基因检测技术优势,在临界风险、高危人群中开展检测工作,降低病残儿出生。结果 (1)应用上述方法对24 542例孕妇进行产前无创产前基因检测,高风险者共354例,检出率为1.44%。包括21-三体高风险孕妇187例;18-三体高风险孕妇46例;13-三体高风险孕妇17例;性染色体异常104例。(2)328例通过羊水穿刺细胞培养,确诊结果:唐氏综合征178例,18三体综合征43例,13三体综合征10例,性染色体异常49例,均已终止妊娠。结论这种依靠政府财政投入,减少个人承担费用,发挥无创产前基因检测对染色体非整倍体疾病的检出率高,具有高特异性、高敏感性及无创取样等优点,在二级出生缺陷防控中,具有重要政治意义和经济、社会效益。
