Abstract
Background:
Psychiatric disorders such as schizophrenia, bipolar disorder, major depressive disorder (MDD), and autism spectrum disorder (ASD) are complex conditions with both genetic and environmental etiologies. Advances in genomic technologies have enabled researchers to explore the genetic architecture underlying these conditions.
Objective:
This article aims to examine the progress in genetic research on psychiatric disorders, highlight key findings from genome-wide association studies (GWAS), and discuss the limitations and ethical considerations surrounding the interpretation and application of genetic data.
Methods:
A comprehensive literature review was conducted of peer-reviewed GWAS, candidate gene studies, and large-scale consortia findings from the past 15 years. Statistical data were extracted and analyzed to compare cross-disorder genetic overlaps and identify unique genetic markers.
Results:
Thousands of genetic loci associated with psychiatric conditions have been identified. Polygenic risk scores (PRS) are emerging tools with predictive potential but remain limited in clinical utility. Shared genetic pathways across disorders suggest pleiotropy. Tables summarize the top loci and PRS performance.
Conclusion:
While genetic research has significantly enhanced our understanding of psychiatric disorders, clinical translation remains a challenge due to genetic complexity, population bias, and ethical dilemmas. A balanced approach integrating genetics with environmental and clinical data is essential.
