The completion of the Genome India Project marks a significant milestone in the country’s scientific and health sectors. Launched back in 2020, this ambitious initiative aimed to sequence the genomes of 10,000 Indians, culminating in January 2025. With the Indian population being one of the most diverse globally, the project's success opens the door for new insights and advances in healthcare.
Bratati Kahali, geneticist and computational biologist at the Indian Institute of Science, served as one of the principal investigators of the Genome India Project. She emphasized the project's importance, stating, "The databases [describing] the global genomics landscapes are extremely Eurocentric, with very few numbers of genetic variations captured from Indians." This situation has placed Indian genetic diversity on the sidelines for far too long, and the project aims to rectify this by providing meaningful data relevant to one-fifth of the world’s population.
Launched to analyze genetic differences across 83 communities, the initiative brings together diverse populations, linking genetic makeup with their susceptibility to diseases such as cancer and neurodegenerative disorders. Sridhar Sivasubbu, retired genomics researcher, reflected on the necessity of such research, expressing, "We represent a significant percent of the world population, one fifth of the world. It is time we filled the gap, and filling the gap started in 2009." This acknowledgment highlights the pressing need for comprehensive genomic studies within India.
The methodology employed included advanced next-generation sequencing technologies, which facilitated detailed genetic analysis. The efforts were led by various research institutes, collaborating to gather samples from both urban areas and distant rural tribes. This task was not simple; researchers navigated remote locations, often waiting for the right season, and sought permissions from local authorities.
With respect to the findings, the sequencing data unveiled hundreds of millions of genetic variants, of which around 27 million are relatively rare and linked to specific diseases. Remarkably, seven million of these variants are novel, previously unrecorded globally, which presents exciting opportunities for future research. Mohammed Faruq, clinical genomics researcher at the Institute of Genomics and Integrative Biology, confirmed this potential, stating, "Understanding our own people’s health at a genomic level is going to revolutionize [healthcare]." This revolution may change how healthcare is approached across India, particularly by enabling personalized medicine.
Genomic comparisons have illustrated how Indian populations exhibit distinct ancestries corresponding to linguistic and geographical diversity. With this data stored digitally for future research, it enhances the capability for precision medicine, guiding healthcare workers and researchers to create customized treatment plans based on genetic backgrounds.
Although only about two percent of India’s diverse communities were sequenced, the project revealed the urgent need for similar initiatives. Faruq forecasts expansion aspirations, noting, "This is not the complete spectrum; this is just the beginning.” The groundwork laid by the Genome India Project is pivotal, not only for future genomic research but also for changing how Indian health concerns are recognized on the global stage.
Many researchers, such as Harsh Sheth of the Foundation for Research in Genetics and Endocrinology Institute of Human Genetics, commended the project's tremendous achievement. Sheth remarked, "The 10,000 will most likely not capture all possible pervasive diversity there is, but it gives you a beautiful flavor of what they’re really like if you want to dig deep." The foundation of knowledge established by the Genome India Project serves as the groundwork for future genomic initiatives aimed at embracing the vast genetic diversity across the Indian population.
Overall, the Genome India Project stands as a landmark effort toward correcting the historical oversight of Indian genetic data on the global genomics platform. It sets the stage for personalized treatments, guides research endeavors, and empowers communities to understand their health risks and genetic variations. Indeed, this project signifies not only advancement in genetics but also reflects India’s commitment to being at the forefront of modern research, embracing its vast and rich diversity.
