概括

基于trio的基因组测序有效地识别了致病性删除,包括马赛克的删除,被外基因组测序遗漏. 这种方法有助于在其他方法失败时诊断遗传疾病.

科学领域:

遗传学是一个遗传学.
基因组医学是基因组医学.

背景情况:

外体序列测序是诊断遗传疾病的常见工具.
然而,它有时无法识别引起疾病的变体,需要采用替代方法.

研究的目的:

为了证明三基基因组测序 (GS) 在识别致病性缺失方面的实用性.
为了突出检测出被外体序列测序遗漏的马赛克删除.

主要方法:

基于三元的基因组测序在两个不相关的家族中进行.
综合基因组学查看器,断点PCR,定量PCR和数字PCR被用于分析和确认删除.

主要成果:

病原性缺失,包括一个在外体覆盖区域之外的缺失和一个涉及单个外体的缺失,GS.成功地确定了.
在两个家族中都检测到了马赛克删除,并通过各种分析和实验方法证实了这一点.

结论:

三基基因组测序是基因分析的宝贵工具,特别是当外基因组测序不足时.
这项研究证实了GS与复杂遗传疾病诊断的确认方法相结合的好处.

Mismatch Repair

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Gene Conversion

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
