まとめ
直接消費者向け遺伝子検査(DTC-GT)の結果は、医療専門家や家族と頻繁に共有される。DTC-GTは
科学分野:
- 遺伝学とゲノミクス
- 医療システム研究
- 消費者健康
背景:
- 直接消費者向け遺伝子検査(DTC-GT)は、ますます入手しやすく、手頃な価格になっている。
- DTC-GT企業は、消費者に結果の解釈のために医療専門家に相談することをしばしば推奨している。
- この傾向は、医療システムの利用とリソース配分に影響を与える可能性がある。
研究 の 目的:
- DTC-GT消費者の共有行動を系統的にレビューすること。
- DTC-GT消費者との医療専門家の経験を理解すること。
- DTC-GT後の結果検証や臨床的処置を含む医療利用を評価すること。
主な方法:
- 2009年から2022年の間に発表された40の記事の系統的レビューを実施した。
- 消費者の共有パターン、医療専門家とのやり取り、および医療利用に焦点を当てた。
- PROSPERO(CRD42021517079)で系統的レビューを登録した。
主要な成果:
- 医療専門家とのDTC-GT結果の共有は1%から57%の範囲であり、最も一般的にはプライマリケア提供者と共有された。
- 医療専門家の19%から76%がDTC-GT消費者の結果共有の経験を報告した。
- 家族(パートナー、親、兄弟)との共有は高く(18%-98%)、遠い親戚との共有は少なかった。
- 結果の検証と臨床的処置の事例が指摘された。
結論:
- DTC-GTの医療システムへの影響に関する初期の懸念は、完全には実現していない。
- 消費者が医療専門家に相談する増加傾向は、準備と政策策定を必要とする。
- 将来の研究では、方法論を標準化し、米国外への地理的範囲を広げるべきである。

Behavioral Genetics and Its Designs
994
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.

Genome-wide Association Studies-GWAS
15.3K
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.
GWAS does not require the identification of the target gene involved in...

Genetic Screens
5.6K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
