Incomplete Coverage of Candidate Genes: A Poorly Considered Bias
Author Information
Author(s): Drago Antonio De Ronchi, Diana Serretti, Alessandro
Primary Institution: Institute of Psychiatry, University of Bologna, Italy
Hypothesis
The hypothesis is that the incomplete coverage of genetic variations within candidate genes is a significant bias in genetic association studies.
Conclusion
The study concludes that a more complete analysis of gene variations is necessary to improve the reliability of genetic association studies in psychiatry.
Supporting Evidence
- Genetic association studies have shown inconsistent results due to methodological biases.
- Candidate gene approaches have yielded some informative genetic variations.
- Recent literature underestimates the importance of complete gene coverage.
Takeaway
Scientists are trying to understand how our genes affect mental health, but they often miss important parts of the genes. This study says we need to look at all parts of the genes to get better answers.
Methodology
The authors surveyed recent literature on genetic association studies focusing on candidate genes and their coverage of genetic variations.
Potential Biases
The study highlights the risk of incomplete gene coverage leading to biased results in genetic association studies.
Limitations
The study primarily discusses methodological biases without providing new empirical data.
Participant Demographics
The study mentions a sample size threshold of about one hundred patients as a criterion for inclusion in the literature survey.
