概括

遗传异质性使听力损失基因识别复杂化. 这项研究研究了DFNA33位点,发现ATP11A中存在一种深层内在变异,不会导致听力损失,这表明其他因素也参与其中.

科学领域:

遗传学是一个遗传学.
耳鼻喉科耳鼻喉科耳鼻喉科
分子生物学分子生物学

背景情况:

鉴定听力损失的因果基因是具有挑战性的,因为遗传异质.
已经绘制了听力损失的众多遗传基因位置,但许多基因缺乏确定的因果基因,尽管测序方面取得了进展.
2009年绘制的DFNA33位点含有ATP11A,这是最近与自体主导性听力损失和听力神经病变2型相关的基因.

研究的目的:

调查DFNA33位点是否与ATP11A基因有关.
为了确定DFNA33位点的家庭中听力损失的遗传原因.

主要方法:

来自原始DFNA33位点研究的家族成员的全基因组测序.
在ATP11A中对功能拼接的深层内部变体的分析.
在DFNA33家族谱系中重新评估单元型和重组事件.

主要成果:

在ATP11A中发现了一种深层内部变异,但它表现出功能正常的拼接.
对DFNA33家族谱系的重新分析揭示了不太可能发生的重组事件 (两个双,一个三重).
鉴定到的ATP11A变体不太可能是DFNA33基位家族中听力损失的原因.

结论:

由于ATP11A的变异,DFNA33位点可能无法解释.
该研究强调需要重新检查历史遗传位置和家族,以解决以前绘制的区域.
解决历史位置可以提供关闭,并推进对遗传性听力损失的理解.

关键词:

在 ATP11A 中,在 DFNA3333 的位置上.基因组测序是指对基因组进行测序.单种类型分析分析.遗传性听力损失是一种遗传性听力损失.没有解决的聋 loci.

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Restarting Stalled Replication Forks

Restarting Stalled Replication Forks

DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart,...

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
