DNA Testing for Preventative Health: Do Outcomes Justify Continued Investment?
IEEE Pulse
|November 20, 2023
Summary
Polygenic risk scores (PRS), which analyze multiple DNA segments, show promise for predicting disease susceptibility. The UK is exploring PRS for public health, but its investment value is under evaluation.
Area of Science:
- Genetics
- Public Health
- Preventive Medicine
Background:
- Consumer genetic testing for ancestry is common.
- Genes may indicate susceptibility to serious diseases.
- Polygenic risk scores (PRS) analyze multiple DNA segments.
Purpose of the Study:
- To evaluate the role of polygenic risk scores (PRS) in public health.
- To assess the potential of PRS in preventive medicine.
- To determine the investment value of PRS technology in the UK.
Main Methods:
- Sequencing multiple parts of an individual's DNA.
- Generating polygenic risk scores (PRS).
Main Results:
- PRS are proposed to predict susceptibility to diseases like type 1 diabetes, cardiovascular disease, and cancer.
- The UK is making significant investments in this technology.
Conclusions:
- Polygenic risk scores (PRS) could revolutionize preventive medicine.
- The ultimate value and effectiveness of PRS for public health remain under investigation.

Preventive Healthcare Services
1.0K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Next-generation Sequencing
89.0K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

DNA Damage can Stall the Cell Cycle
9.2K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Longitudinal Research
12.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Sensitivity, Specificity, and Predicted Value
411
In healthcare diagnostics, laboratory tests play a crucial role in identifying and diagnosing a wide range of medical conditions. However, interpreting test results is not always straightforward. An abnormal test result does not always confirm the presence of a disease, just as a normal result does not guarantee its absence. To assess the reliability of these diagnostic tools, healthcare practitioners rely on two key statistical indicators: sensitivity and specificity.
Sensitivity is the...
