- 遗传学 是一个遗传学.
- 在瘤学瘤学.
- 流行病学 流行病学
背景情况:
- 乳腺癌是台湾女性最常见的癌症.
- 遗传变异影响乳腺癌风险,但亚洲人群的研究有限.
- 多基因风险评分 (PRS) 是评估癌症遗传倾向的新兴工具.
研究的目的:
- 为台湾人群开发和验证乳腺癌特定的PRS.
- 为了确定最有效的PRS预测乳腺癌风险在这个人口.

Genome-wide Association Studies-GWAS
12.4K
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
14.0K
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,...
