Methodology and Implementation of the Genome India Project

Whole Genome Sequencing Process

Whole Genome Sequencing (WGS) is a comprehensive method that involves determining the complete DNA sequence of an organism’s genome at a single time. This process includes sequencing all of an organism’s chromosomal DNA, as well as DNA contained in the mitochondria and, for plants, in the chloroplast. The steps involved in WGS include:

1. DNA Shearing: The DNA is fragmented into smaller pieces using molecular scissors.
2. DNA Barcoding: Small pieces of DNA tags, or barcodes, are added to identify which piece of sheared DNA belongs to which sample.
3. DNA Sequencing: The bar-coded DNA from multiple samples is combined and put in a DNA sequencer, which identifies the bases (A’s, C’s, T’s, and G’s) that make up each sequence.
4. Data Analysis: Scientists use computer analysis tools to compare sequences from multiple samples and identify differences. This helps in understanding how closely related the samples are, and how likely it is that they are part of the same genetic group or outbreak.

The importance of WGS lies in its ability to provide detailed and precise data for identifying outbreaks sooner and characterizing bacteria as well as tracking outbreaks. This greatly improves the efficiency of surveillance.

Interdisciplinary Approach

The Genome India Project employs an interdisciplinary approach that combines genomics, computational biology, bioinformatics, and statistical modeling. This approach is essential for the systematic acquisition of data made possible by genomics, proteomics, electronic health records, biosensors, and imaging technologies, which has created a significant gap between available data and their biomedical interpretation. Computational and statistical approaches are crucial for understanding biological and biomedical systems and help close this gap. Activities include modeling biomedical and biophysical processes, large-scale database development, data mining, machine learning, and high-performance computing.

Collaborative Effort Across India

The Genome India Project is a collaborative effort involving over 20 research institutes across India. This national project, funded by the Department of Biotechnology, Government of India, aims to identify genetic variations through whole genome sequencing of 10,000 representative individuals across India in the first phase of the study. The collaboration among these institutes is represented in the project’s aim to create an exhaustive catalog of genetic variations (common, low frequency, rare, single nucleotide polymorphisms or SNPs, and structural variations) in Indians. This collaborative effort is crucial for creating a reference haplotype structure for Indians, which can be used for imputing missing genetic variation in future studies.

The Genome India Project exemplifies the significance of collaborative, nation-wide, mission-oriented scientific partnerships. It is spearheaded by the Centre for Brain Research at the Indian Institute of Science, Bangalore, acting as the central coordinator between the collaborating institutions. This consortium approach exemplifies the importance of synergy among different components to generate a better understanding of how genomic variation affects genome function.
