The Emerging Role of Glycomics in Precision Medicine

Glycomics, the particularly refers to compendious study of glycans and their associated structures. The emerging field is a wider and promising field in understanding various biological processes. Glycans are complex carbohydrate molecules, ultimately play an incumbent role in cellular communication, immune responses, and disease progression. Several behavioral disorders, such as autism spectrum disorders and schizophrenia, have demonstrated alterations in glycosylation patterns, which could serve as indicators of disease onset or progression. Similarly, in infectious diseases, pathogens exploit host glycan pathways for adhesion, invasion, and immune evasion, presenting an opportunity to identify novel diagnostic and therapeutic targets. In the context of chronic and acute diseases, aberrant glycosylation has been linked to conditions such as cancer, diabetes, and cardiovascular diseases, where glycans influence cellular signaling and pathological mechanisms. This chapter delves into the recent advances in glycomic profiling technologies, including mass spectrometry and glycan microarrays, which have significantly enhanced our ability to detect and characterize glycans with high precision. Furthermore, it highlights the challenges in translating glycomic data into clinical applications, emphasizing the need for standardized protocols and interdisciplinary convergence with genomics, proteomics, and metabolomics. By spotlighting key discoveries, this review showcases glycomics' transformative potential in redefining medical diagnostics, prognostics, and therapeutics.
