- 遗传学 是一个遗传学.
- 免疫学 免疫学 免疫学
- 胃肠病学 胃肠病学
背景情况:
- 观察性研究表明,在原发性胆道胆炎 (PBC) 患者中,斯约格伦综合征 (SjS) 的患病率较高.
- SjS和PBC之间的因果关系需要进一步调查.
研究的目的:
- 调查一级胆道胆道炎 (PBC) 和肖格伦综合征 (SjS) 之间的双向因果关系.
- 使用孟德尔随机化 (MR) 分析来评估遗传易感性.
主要方法:

Genome-wide Association Studies-GWAS
13.3K
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.

Single Nucleotide Polymorphisms-SNPs
15.0K
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,...

Autoimmune Disorders
417
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
