概括
携带一种囊性纤维化基因变异 (异胞体) 个体的个体通常不会面临更高的相关疾病风险. 需要进一步的研究,以了解一些异生菌中呼吸道和传染病的风险增加.
科学领域:
- 遗传学 是一个遗传学.
- 人口健康 人口健康
- 基因组医学是基因组医学.
背景情况:
- 囊性纤维化 (CF) 是一种常见的自体相衰退性疾病.
- 数以百万计的个人对CFTR基因变异异质,但他们的疾病风险尚不清楚,特别是在非欧洲人群中.
- 了解CFTR异合体风险对于改善不同群体的管理策略至关重要.
研究的目的:
- 调查携带单一致病性CFTR基因变异与整个现象中各种疾病的风险之间的关联.
- 在不同的遗传祖先群体中分析这些关联.
主要方法:
- 一项基因关联研究,使用来自我们所有人研究计划的全基因组测序数据,与电子健康记录 (EHR) 相关联.
- 使用参考数据集推断遗传血统 (1000个基因组项目,人类基因组多样性项目).
- 进行了多变量调整的全现象关联研究 (PheWAS),以计算疾病风险的几率比率 (OR).
主要成果:
- 分析了317,964名成年参与者,确定了7,957名CFTR异构体.
- 总体上或在特定的祖先群体中,没有发现CFTR异性和疾病风险之间的统计学上显著的关联.
- 虽然某些CF相关疾病在某些异构体 (例如,过敏性支气管肺阿斯伯吉洛症,支气管切除症) 中显示出略有增加的风险,但与同构体相比,效应大小非常小.
结论:
- 一般来说,CFTR异构体在成年时不会显著增加CF相关疾病的风险.
- 在一些异构卵性动物中,特定的呼吸道和传染病的风险增加需要进一步调查潜在因素.

Cystic Fibrosis: Pathogenesis
358
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Cystic Fibrosis: Management
220
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Genome Copying Errors
4.4K
DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their survival. Therefore, the copying errors are checked and repaired at three levels.

Sex-linked Disorders
102.9K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
