- 遗传流行病学遗传流行病学
背景情况:
- 观察性研究表明,血哈普托格洛宾与多发性硬化症 (MS) 之间存在联系.
- 哈普特蛋白在多发性硬化症的发病过程中的作用是显著的,但其因果作用仍未得到证实.
研究的目的:
- 研究血哈普托格洛宾与多发性硬化症 (MS) 的风险和严重程度之间的潜在因果关系.
主要方法:
- 采用双样双向孟德尔随机化 (MR) 方法.

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.

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
