项发表于国际杂志Clinical Chemistry上的研究论文中,来自普利茅斯大学等处的科学家通过研究开发出了一种简便准确且低风险的血液检测技术,其可以帮助孕妇进行产前诊断,帮助检测胎儿的血型、性别及遗传状况。相比传统的羊膜穿刺术而言,这种新型的DNA测试技术是非侵入性的,其主要利用一种穿刺针就可以完成检测,而且风险极低。

这种新型检测技术可以用于处于X染色体连锁隐性基因疾病风险的母亲中,包括血友病和杜氏肌营养不良,同时还适用于患溶血性疾患的新生儿的检测;当母亲得到医生的安排或处于怀孕早期时,该技术就可以利用来自母亲的血液进行检测。Neil Avent教授表示,尽管十多年来我们可以利用孕妇的外周血来检测胎儿的血型和性别,但本文研究为我们提供了一种准确且敏感性的检测胎儿机体DNA的血液检测方法,利用该技术或可对别的疾病进行检测,而且相比当前的非侵入手段而言这种技术价格较为低廉。

研究者补充道,这种新型技术为早期鉴别婴儿的一些疾病提供了一种相对低风险的方法,其随后还可以帮助进行早期诊断,同时开发新型疗法来对孕妇和婴儿带来益处;从客观角度来讲,这种技术可以促成对孕妇患者的临床管理和治疗。

最后研究者Ross Welch博士说道,进行这样一种新型检测是怀孕个体可以选择的一个项目,因为怀孕的人们有权利知道未来要发生什么,当然本文研究中研究人员开发的这种新型检测技术不仅是有效的,而且还会对母亲和婴儿带来极低的健康风险。

罗氏收购Ariosa诊断公司,进军非侵入性产前诊断(NIPT)市场

瑞士制药巨头罗氏(Roche)近日宣布收购美国Ariosa诊断公司,此举将使罗氏涉足非侵入性产前诊断领域。Ariosa是一家分子诊断公司,开发产前检测,评估唐氏综合症(Down syndrome)及其他遗传异常的风险。该笔交易的财务细节尚未披露。罗氏诊断(Roche Diagnostics)高管Roland Diggelmann在声明中称,收购Ariosa是罗氏致力于推进分子诊断的另一个例子。Ar

AJOG:产前诊断领域,核型分析 vs. 基因组杂交(Meta)

产前诊断作为新兴领域,虽然年轻,但其发展势头迅猛。随着环境的恶化、孕妇的高龄化以及其他因素,缺陷儿越来越多,大体结构上的畸形可以通过超声得到明确诊断,可是对于染色体或是基因层面的异常,却需要依靠更高科技的技术。目前对于染色体结构、数目异常诊断的金标准是核型分析,同时还有无创DNA、荧光原位杂交FISH、RT-PCR、比较基因组杂交CGH、基因芯片等众多基因领域新兴的技术手段。近期Saldarria
