まとめ
前立腺がん (PCa) 患者における病原性生殖線変異 (PGV) の割合は,以前に報告されたより低かった. 年齢と人種は PGV ステータスの予測因子であり,攻撃的なPCa のための普遍的な遺伝子検査を支持しました.

研究 の 目的:
- PCa患者の現実の世界でのPGV率を決定する.
- PCa患者のPGVキャリア状態の臨床予測要因を特定する.
主な方法:
- 4634人のPCaリスク遺伝子の遺伝子検査結果を分析した.
- 臨床的,病理的,および家族歴のデータは,医療記録から抽象化されました.
- 統計的検査を用いて,PGV率をがんのない男性と比較した.
主要な成果:
- PCa患者の5. 4%が12のPCaリスク遺伝子でPGVを有しており,BRCA2,ATM,CHEK2,リンチ遺伝子,BRCA1が最も一般的であった.
- 白人 (3. 3%) と黒人 (3. 7%) のPCa患者では,PGVの割合が著しく高かった.
- 診断時の年齢と自己認識した人種は,PGV状態と有意に関連していました.

Single Nucleotide Polymorphisms-SNPs
15.8K
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,...

Cancers Originate from Somatic Mutations in a Single Cell
12.6K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Genome-wide Association Studies-GWAS
14.1K
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.

Cancer Prevention
6.3K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Genetic Variation
387
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.

Comparing Copy Number Variations and SNPs
17.9K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
