A Review on the Challenges in Indian Genomics Research for Variant Identification and Interpretation

Area of Science:

• Genomics and Bioinformatics
• Medical Genetics
• Computational Biology

Background:

• Genomic data offers significant potential for advancing healthcare, including disease prevention, diagnosis, and treatment optimization.
• A major challenge in India is the scarcity of population-wide genotype-phenotype correlations, impeding effective clinical decision-making.
• Accessible genome sequencing technologies are available, yet critical variant information for major diseases remains absent from public databases.

Purpose of the Study:

• To highlight the challenges in leveraging genomic data for healthcare in India.
• To emphasize the need for genotype-phenotype correlations and centralized variant databases.
• To discuss the role of machine learning in analyzing complex genomic datasets.

Main Methods:

• Population-wide sequencing of Indian genomes to identify and validate genetic markers.
• Application of machine learning algorithms to analyze integrated genotype, gene expression, demographic, clinical, and pathological data.
• Development of predictive models for risk stratification and personalized therapy design.

Main Results:

• Lack of genotype-phenotype correlations and accessible variant databases hinders the translation of genomic information into clinical practice in India.
• Machine learning is crucial for analyzing large-scale genomic data and developing predictive models for disease risk and treatment.
• Centralized variant databases are essential for early detection and mitigation of health risks.

Conclusions:

• Addressing the dearth of public databases, machine learning expertise, computational resources, and medical community awareness is vital for advancing genetic research in India.
• Developing centralized variant databases and fostering collaborations are key steps towards realizing the potential of genomic medicine in India.
• Implementing population-wide sequencing and advanced analytical methods will enable personalized preventive and therapeutic strategies for Indian populations.
