概括
不一致的基因,在较新的人类基因组组合中重新归类为蛋白质编码,但不是较旧的基因组,通常被忽视. 这影响了临床遗传学,因为许多这些被忽视的基因具有临床相关性.
科学领域:
- 基因组学就是基因组学.
- 人类遗传学 人类遗传学
- 生物信息学是一种生物信息学.
背景情况:
- 许多国际项目更喜欢GRCh37人类基因组组装,而不是GRCh38.8等更新版本.
- 不一致的基因 (DGs) 在较新的组合中编码蛋白质,但不是GRCh37,导致它们在基因组资源和变异优先级工具中被遗漏.
研究的目的:
- 修复组合基因在GRCh37和GRCh38之间有注释差异.
- 检查这些不一致的基因的临床和表型相关性.
主要方法:

- 与RefSeq转录匹配不一致的基因.
- 评估不一致基因的临床和表型相关性.
主要成果:
- 确定了337个基因,这些基因被重新归类为GRCh38中的蛋白质编码,但不是GRCh37.
- 194个不一致的基因已经改变了HGNC基因符号.

Genome Annotation and Assembly
18.9K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Evolutionary Relationships through Genome Comparisons
5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Next-generation Sequencing
91.6K
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.
