GenomeIndia Project

The GenomeIndia project has revealed findings regarding the genetic diversity of the Indian population. Published in April 2025, this extensive study analysed the genomes of 10,074 individuals from diverse backgrounds. It included both tribal and non-tribal populations, providing vital information about genetic variants linked to health and disease.

GenomeIndia Project

The GenomeIndia project is a collaborative initiative involving 20 institutions across India. It aims to understand the genetic makeup of the Indian population. Blood samples were collected from approximately 20,000 individuals, leading to the sequencing of 9,772 genomes. This dataset is crucial for studying complex diseases and their genetic underpinnings.

Population Sample and Diversity

The study included 85 populations, comprising 32 tribal and 53 non-tribal groups. Each group contributed about 100 samples. The median samples were 159 from non-tribal populations and 75 from tribal populations. This approach ensures a broad representation of India’s genetic diversity.

Genetic Variants Identified

Researchers identified 180 million genetic variants from the sequenced genomes. Of these, 130 million variants were found in non-sex chromosomes, while 50 million were located in sex chromosomes. Some variants are associated with diseases, while others are rare or unique to specific communities in India.

Implications for Health and Medicine

The findings have implications for health. Certain genetic variants may indicate susceptibility to infectious diseases, while others could suggest resistance. About these variants will aid in developing targeted therapies and low-cost diagnostic tools. This could enhance personalised medicine in India.

Future Directions of the Project

The GenomeIndia project will focus on identifying functionally relevant variants. Researchers aim to correlate these variants with disease associations and therapeutic responses. This effort will help in constructing a panel of variants useful for future genetic studies and diagnostics.

Real-Time Applications of Genome Data

The genome data can facilitate the development of diagnostic kits tailored to specific diseases. It will also improve predictions regarding drug responses among individuals. This research paves the way for precision medicine, enhancing healthcare outcomes for the Indian population.

Collaborative Efforts in Genome Sequencing

Key institutions involved in the genome sequencing include the Centre for Brain Research at IISc Bangalore and the Centre for Cellular and Molecular Biology in Hyderabad. Their collaborative efforts have been instrumental in achieving the project’s goals.
