Multi-omics for disease subtyping and classification

In the era of precision medicine, the classification and subtyping of diseases have transcended beyond the conventional approaches that were heavily reliant on symptomatic observations and singular biomarker assessments. The advent of multi-omics technologies has ushered in a transformative period in medical research and diagnostics, enabling a more nuanced understanding of disease mechanisms. Multi-omics encompasses the integrated analysis of datasets from genomic, transcriptomic, proteomic, and metabolomic studies, each offering a unique vantage point into the cellular and molecular landscape of tumors. This comprehensive approach is particularly salient in the context of brain tumors, where the correlation between genotype and phenotype is not always linear, and the interplay between various biological layers can illuminate the pathogenesis and progression of the disease. In this chapter, we explore the burgeoning field of precision medicine for different diseases, emphasizing the revolutionary role of multi-omics in unraveling disease complexity and guiding the transition toward more personalized and effective healthcare solutions through precise disease subtyping.
