Abstract
In recent years, the rapid development in bioinformatics technologies has provided new perspectives and methods for studying complex diseases. This study aims to systematically review the latest advances of bioinformatics in the study of complex diseases and explore its applications in disease mechanism resolution, biomarker discovery and personalized therapy. By integrating multi-omics data analysis, machine learning algorithms and network biology approaches, this study focuses on the synergistic effects of multidimensional data including genomic, transc riptomic, epigenetic group and proteome in disease research. It is found that the deep learning-based gene variant prediction model significantly improves the identification accuracy of pathogenic mutations; the application of single-cell sequencing technology reveals the molecular mechanism behind the disease heterogeneity; and the network analysis method integrating multi-omics data successfully constructs the molecular interaction map of multiple complex diseases. In particular, this study innovatively proposed a graph neural network-based disease-gene association prediction fr amework, making a breakthrough in the study of complex diseases such as Alzheimer's disease and type 2 diabetes.
