科学领域:
- 遗传学 遗传学 是一个
- 在瘤学瘤学.
- 生物信息学是一种生物信息学.
背景情况:
- 前列腺癌 (PCa) 在全球范围内是一个重大的健康问题.
- 遗传因素在PCa的发展中起着至关重要的作用.
- 全基因组关联研究 (GWAS) 已经确定了许多与PCa风险相关的单核酸多态 (SNP).
研究的目的:
- 开发和验证多基因风险评分 (PRS) 以估计对前列腺癌 (PCa) 的遗传易感性.
- 评估PRS在台湾人口中的预测性能.
主要方法:
- 来自台湾生物库 (TWB) 的1,015名PCa患者和1,015名年龄匹配对照组被用于PRS发展.
- 组建了一个独立的验证队列,以确认PRS的性能.
- 进行了基因型和归算,分析了大约69万个SNP和1500万个归算的SNP.

Genome-wide Association Studies-GWAS
14.2K
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.

Polygenic Traits
66.5K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Single Nucleotide Polymorphisms-SNPs
15.9K
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,...
