下一代的希望:核型定位-胚胎植入前遗传学诊断(Karyomapping PGD)的故事

与大多数科学技术一样,karyomapping PGD(核型定位-胚胎植入前遗传学诊断)涉及到一些复杂而精确的参数,但若谈及它对患者生活的改善,那可谓是重拳出击。

最近几篇文章报道了一些因为PGD的使用,从而在出生时幸免于患上特定遗传疾病的新生婴儿。两个澳大利亚的家庭因此能够保证他们自身所携带的遗传疾病不被传递给他们的孩子,从而确保家庭未来后代的安全。因此,标题用了“让诅咒在这里终止”作为背景,我们先简单介绍一下karyomapping PGD到底是什么,以及如何使用它来确保健康的未来。

根据严重程度的不同,遗传性疾病可能会对整个家庭带来灾难性的影响,包括心理、社会和/或经济影响。那些携带遗传病性状的个体,看到自己的亲人受到严重疾病的折磨,往往会失去组建自己的家庭的愿望,因为害怕把患病基因遗传给未来的孩子。

这就是干预能发挥作用的地方,它为那些可能将严重遗传病传递给下一代的夫妇提供了确定性。karyomapping(核型定位)是一种胚胎植入前遗传学诊断(PGD)技术,配合体外授精(IVF)使用。它的原理是在携带缺陷基因的染色体上寻找独特的遗传标记,就像指纹。利用这些标记,人们可看到感兴趣的基因所在的染色体片段,并确定这个片段是遗传自父亲还是母亲。这让科学家能够确定该胚胎是遗传了基因的正常版本,还是突变版本,从而找出哪个胚胎受影响,而哪个不受影响——这可能是植入的最佳候选。

通过体外授精获得的胚胎须经过活检步骤,也就是取出胚胎上一个或多个细胞,进行特定疾病的检测。有了这种技术,准父母能够在胚胎植入和怀孕之前检测胚胎的疾病状况。

在上面提及的例子中,一个家庭来自墨尔本,而另一家来自悉尼,他们都在墨尔本IVF机构寻求治疗。Mike和Victoria来自墨尔本,在失去了他们的第一个孩子Charlie后开始接受治疗,Charlie患上了一种被称为先天性肌无力综合征(CMS)的疾病,这是一种神经肌肉疾病,特点是虚弱和疲劳,而问题出自神经和肌肉细胞相连的地方。直到大儿子去世之前,这对夫妇一直没有意识到他们双方都是这种罕见疾病的携带者。他们选择接受karyomapping, 因为他们还想要一个孩子,但要确保这个孩子没有遗传这种疾病。

巧合的是,在Mike和Victoria诞下健康男婴的同一天,Jono和Alex这对悉尼夫妇也诞下了一个健康女婴,未携带她母亲的BRCA1突变。在Alex发现她遗传了家族的BRCA突变后,决定让“诅咒”在她这里终止,也就是说她将是这个家族中最后一名携带突变的女性。尽管并非所有BRCA突变都有害,但某些基因改变的确有着严重的后果,明显提高乳腺癌卵巢癌的风险。在实施预防性的手术以降低患癌机会之前,Alex希望拥有自己的家庭。为了确保她的孩子没有遗传到这种突变,这对夫妇使用karyomapping来选择无突变的胚胎。

这种技术为那些携带可怕的遗传病的父母带来了新的希望。让他们相信,他们的子女及后代将免于这些疾病。对于某些人来说,PGD是唯一的希望。

图片来源:medicalxpress.com 近日,发表在国际杂志Scientific Reports上的一项研究论文中,来自新加坡的研究人员通过研究首次在体外恢复了对胚胎形成的两个关键必须过程,研究小组不仅实现了控制干细胞向其他细胞类型的分化潜力,而且还将这些转化的细胞进行了成功地迁移。 研究者Jackie Y. Ying表示,胚胎意外接触干扰胚胎发育的化合物,比如沙立度胺,就会导致胎

Nature:再掀学术伦理之争!中国科学家瞄准人类胚胎基因改造

中国科学家走在世界的第一位,首次报道成果对人类胚胎的基因进行改造。该项研究结果在线发表在最新一期 Protein & Cell 杂志上。这一消息正式确认了科学界关于对人类胚胎基因研究工作正在开展的谣言,而后者因伦理问题在上个月引起了激烈的讨论。 在这项由中山大学基因功能学教授Jun-jiu Huang所主持的研究中,研究人员利用来自当地生殖医疗机构“不能存活”的胚

JAMIA:出生月份原来真的可以影响一个人的健康

出生月份可显著影响个体一生所患的疾病,先前的研究表明出生月份与许多疾病,包括动脉粥样硬化、哮喘、多动症以及近视有关,此外尚有许多疾病并未明确与出生月份之间的关系。本次回顾性研究的目的是为了探讨季节对个体出生和一生所患疾病的影响。

中山大学生物学副教授黄军就等,利用最新的基因编程技术CRISPR/Cas9修改了β珠蛋白基因,该基因突变会导致地中海贫血。显然这一技术是希望对这一突变基因进行修改,目的是实现对地中海贫血这一遗传病的基因治疗。地中海贫血中国南方是儿童中最常见,这是一种可致命的血液遗传性疾病。 该研究论文最近发表在Protein & Cell(蛋白质和细胞)杂志上。这是中国科学家团队首次成功修改人类胚胎的D

Developmental Cell:新的胚胎影像处理技术可提高体外受精的成功率

Developmental Cell:新的胚胎影像处理技术可提高体外受精的成功率来自莫纳大学的生物学家及工程师合作共同研发出一种新的非侵入式的图像处理技术,可直观的看到胚胎的形成过程。该研究发表于《Developmental Cell》。首次,该研究人员发现他们可以在镜下观察到活的哺乳动物胚胎中所有细胞的生长发育活动。这一突破对体外受精(IVF)治疗以及胚胎植入前遗传学诊断(PGD)具有重大意义。
