GenomeIndia Project Findings Published:Nature Genetics released preliminary findings from the GenomeIndia project, sequencing ~10,000 individuals from 85 Indian population groups (32 tribal, 53 non-tribal).
Vast Genetic Diversity: The study identified 180 million genetic variants; 130 million on autosomes and 50 million on sex chromosomes. Some variants are disease-linked, rare, or unique to India/specific communities.
Project Overview: Launched in 2020 by the Department of Biotechnology (DBT), GenomeIndia aims to map the genetic diversity of the Indian population and create a comprehensive reference genome.
Collaborative Effort: Over 20 institutions collaborated in the first phase to sequence 10,000 genomes from 20,000 samples collected.
Data Repository: Genome data is stored in the Indian Biological Data Centre (IBDC) at RCB Faridabad, India’s first national life science data repository.
Significance: Addresses the underrepresentation of Indian genomes in global databases, boosting India’s role in international genomics research.
Variant Analysis: Researchers are investigating the implications of identified variants related to diseases, therapeutic responses, and environmental adaptations. They are constructing a panel of variants for future use in genotyping.
Real-Time Applications: Genome data will be used to develop low-cost diagnostic kits and personalized medicine strategies. It will also improve disease diagnostics and predict drug responses.
Genome Sequencing Explained: Genome sequencing determines the complete sequence of nucleotide bases in an organism’s genome. Whole-genome sequencing (WGS) provides the most comprehensive genetic blueprint.
