Omics and rare diseases: challenges, applications, and future perspectives

Area of Science:

• Genetics and Genomics
• Biotechnology
• Medical Research

Background:

• Rare diseases (RDs) present significant global health challenges due to their heterogeneity, complexity, and limited understanding.
• Typical RDs feature pediatric onset, lifelong impact, multisystemic involvement, and poor prognoses, necessitating advanced research approaches.

Purpose of the Study:

• To review the application of high-throughput omics technologies in studying rare diseases.
• To highlight the potential of omics for improving diagnosis, understanding pathogenesis, discovering biomarkers, and identifying treatments for RDs.

Main Methods:

• Review of high-throughput omics technologies including genomics, transcriptomics, proteomics, metabolomics, and epigenomics.
• Exploration of multi-omics approaches and artificial intelligence (AI) tools for RD research.

Main Results:

• Omics technologies are becoming more affordable and efficient, enabling deeper insights into RDs.
• Multi-omics and AI can drive biomarker discovery and personalized treatment strategies for rare diseases.

Conclusions:

• Rare diseases present a unique opportunity for collaborative, personalized treatment strategies leveraging omics technologies.
• Addressing technical, ethical, legal, and societal challenges is crucial for the successful implementation of omics in RD research.
