概括

基因组解剖测序显著改善了因胎儿异常或围产死亡而经历妊娠终止的家庭的遗传咨询. 这种增强的诊断方法提供了更清晰的复发信息,即使没有特定的遗传诊断.

科学领域:

基因组学就是基因组学.
医学遗传学医学遗传学
生殖医学生殖医学

背景情况:

临床遗传学家在妊娠终止后为胎儿异常或无法解释的围产死亡 (PND) 建议家庭.
标准调查往往仅限于分子分析的使用,使许多案件未得到解决.
澳大利亚基因组解剖研究 (GAS) 调查了先进基因组技术的实用性.

研究的目的:

评估外体和/或基因组测序 (ES/GS) 对临床管理和家长咨询的影响.
评估临床医生提供的关于复发可能性和生殖规划信息的变化.
为了确定基因解剖的价值,超越了确定的遗传诊断.

主要方法:

采用了一种诊断前后研究设计.
在获得ES/GS结果之前和之后,完成了161对临床医生调查.
临床医生报告了复发概率估计和生殖规划建议.

主要成果:

临床医生对PND复发概率的估计在45%的家庭中发生了变化.
只有19%的病例被确定为特定的遗传诊断.
患有复发"未知可能性"的家庭比例显著下降 (26%至15%,p=0.01).
无论诊断如何,向父母提供关于复发和生殖规划的信息都显著增加.
临床医生报告了家长对调查的高感知价值.

结论:

基因组解剖,包括外体和/或基因组测序,显著提高了妊娠终止后家庭的临床咨询.
基因组解剖的实用性超出了确定特定的遗传诊断,改善了复发风险评估和生殖规划建议.
这种方法为家庭提供了有价值的信息,改善了管理和理解,即使在没有确定的遗传发现的情况下.

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

Genomics

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Sanger Sequencing

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
