Tribal Health Challenges
India’s First Tribal Genome Initiative: Gujarat has become the first Indian state to launch a genome sequencing project focused on tribal communities. The initiative addresses high prevalence of inherited disorders caused by endogamous marriages, which reduce genetic diversity. Common conditions among tribal groups include sickle cell anaemia, thalassemia, and G6PD deficiency. Late diagnosis of these diseases often complicates treatment and increases healthcare costs.
Static GK fact: India has over 104 million tribal population, spread across 705 communities as per Census 2011.
Genome Sequencing Approach
The Gujarat Biotechnology Research Centre (GBRC) leads the project under the broader Genome India Project. Over 4,000 biological samples will be collected, with complete genome sequencing of 2,000 individuals across 17 districts. Sequencing identifies gene mutations causing hereditary diseases, enables early diagnosis through targeted DNA panels, and supports genetic counselling for families.
Static GK Tip: The Genome India Project aims to map the genomes of 10,000 Indians to create a comprehensive reference database.
Technology and Infrastructure
GBRC uses advanced long-read sequencers capable of analysing 5,000–10,000 DNA base pairs. These platforms, initially deployed during the Covid-19 pandemic, now facilitate tribal genomic studies. Local infrastructure investments have reduced sequencing costs from ₹85,000 to ₹60,000 per sample. Precision medicine tools developed here can target tribal-specific health needs.
Data Collection and Analysis
The project focuses on diverse tribal groups, with an emphasis on parent–child trios to trace hereditary patterns. DNA samples will be used to create low-cost diagnostic kits, potentially priced between ₹1,000–1,500. Full genome sequencing remains expensive, averaging ₹1 lakh, but these innovations aim to make genetic testing accessible and affordable for tribal populations.
Static GK fact: Long-read sequencing provides more accurate mapping of complex regions of the genome compared to short-read technologies.
Implications for Tribal Healthcare
This initiative marks a major step in applying biotechnology to public health in India. Precision medicine tailored for tribal populations can improve early detection and treatment of genetic disorders. It also paves the way for research on immunity, nutrition, and disease susceptibility among tribal communities.
Static GK Tip: Gujarat hosts over 5.7 million tribal people, concentrated in districts like Dang, Narmada, and Panchmahal.
