The DBT-funded Genome India Project has successfully sequenced 10,000 Indian genomes. This ambitious project, which began in January 2020, is supposed to help find out what lies behind the genetic diversity and disease patterns within the vast population of India. Led by the Centre for Brain Research at the Indian Institute of Science, Bengaluru, along with 20 other institutions, this project is to come up with predictive diagnostic markers through whole-genome sequencing.
- GIP is a pan-India initiative, and it specifically focuses on the whole genome sequencing of representative populations across the country.
- This is going to start with the execution of the whole genome sequencing and subsequent data analysis of 10,000 individuals representing the diverse population of the country.
Genome India Project
The Genome India Project (GIP) was initiated on January 3, 2020, by the Department of Biotechnology (DBT). Led by the Centre for Brain Research at the Indian Institute of Science, Bengaluru, the project aims to sequence 10,000 genomes to understand disease nature in the Indian population and develop predictive diagnostic markers.
Project Initiation and Collaboration
The Genome India Project was initiated by DBT in January 2020 and involves collaboration with 20 institutions across India. The Centre for Brain Research at the Indian Institute of Science, Bengaluru, is spearheading this ambitious initiative to decode the genetic blueprint of the Indian populace.
Objectives and Scope
The primary objective of the Genome India Project is whole-genome sequencing and data analysis of 10,000 individuals. This will help in understanding the nature of diseases in the Indian population and in developing predictive diagnostic markers for various ailments.
Genetic Diversity in India
India’s vast genetic diversity is evident with a population of 1.3 billion, comprising over 4,600 population groups, many of which are endogamous. This genetic diversity contributes to various disease-causing mutations, making the Genome India Project crucial for tailored healthcare solutions.
Data Storage
The Genome India Project PIB will generate a colossal dataset of 8 petabytes, which will be stored at the Indian Biological Data Centre (IBDC) in Faridabad. Inaugurated in 2022, IBDC is India’s first national repository for life science data, ensuring secure and efficient data management.
Significance of the Genome India Project
The human genome project in India is, therefore, very important to understanding the local genetic mutations such as MYBPC3 mutation, which causes early cardiac arrest and is prevalent in 4.5% of the Indian population. The said sector will drive the biology sector in India from USD 10 billion in 2014 to approximately 130 billion USD by the year 2024.
Health Implications
The Genome India Project brings immense health relevance, especially in finding those genetic mutations that are prevalent in India. For example, the MYBPC3 mutation, leading to early cardiac arrest, affects 4.5% of the Indian population, and hence, region-specific genetic research is essential.
Economic Impact
Economically, the Genome India Project positions India as a leader in genetic research, bolstering the biology sector. With the world’s largest genetic laboratory, India’s biology sector is projected to grow from USD 10 billion in 2014 to USD 130 billion by 2024, driving significant economic benefits.
What is Genome Sequencing?
Genome sequencing involves determining the precise order of nucleotide bases in an organism’s genome. Comprising approximately 3 billion base pairs, this sequence encodes essential biological traits, influencing an individual’s physical characteristics and disease susceptibility.
Gene and DNA
DNA (Deoxyribonucleic acid) carries genetic instructions vital for the development, functioning, growth, and reproduction of living organisms. Genes, specific segments of DNA, contain the instructions for producing proteins essential for various biological functions.
Genome
A genome represents the entirety of an organism’s hereditary information, acting as a biological instruction manual inherited from parents. It consists of four nucleotide bases: adenine, cytosine, guanine, and thymine, forming approximately 3 billion base pairs in humans.
Genome Sequencing
Genome sequencing is the process of determining the order of nucleotides within an organism’s genome. This laboratory procedure provides a comprehensive view of an organism’s genetic makeup, facilitating the understanding of its biological traits and disease susceptibilities.
Procedure of Genome Sequencing
The genome sequencing procedure involves several steps: DNA extraction, fragmentation, tagging with fluorescent markers, sequencing, and data analysis. Each step is crucial for accurately determining the genetic sequence of an organism.
DNA Extraction
The first step in genome sequencing is extracting DNA from a sample, typically obtained from blood. This provides the foundational material needed for further genetic analysis.
DNA Fragmentation and Tagging
In the next step, the extracted DNA is fragmented into smaller pieces, which are then tagged with fluorescent markers. These markers aid in identifying and sequencing the DNA fragments.
Sequencing and Reading
Using DNA sequencers, the tagged DNA fragments undergo sequencing, where the nucleotide bases are read. This step is crucial for accurately determining the genetic sequence.
Data Analysis
Finally, computational algorithms are employed to reconstruct the complete genetic sequence from the sequenced data. This analysis provides valuable insights into an individual’s genetic makeup, aiding in various applications.
Applications of Genome Sequencing
Applications of genome sequencing range widely from basic biomedical research to pharmacogenomics and agricultural genomics, and finally to evolutionary biology and conservation biology. Each application uses genetic knowledge to further knowledge and solutions.
Biomedical Research
Genome sequencing in biomedical research helps the elucidation of the genetic basis of diseases. These includes mutation identification and discovery of potential drug targets. It facilitates genetic variation studies associated with complex diseases like cancer, diabetes, and neurological disorders.
Pharmacogenomics
Pharmacogenomics uses genome sequencing to predict how individuals will respond to different drugs based on their genetic makeup. This information can optimize drug selection, dosage, and treatment strategies, leading to more effective and personalized therapies.
Agricultural Genomics
Genome sequencing in agricultural genomics enhances agronomic traits, including disease resistance, yield, and nutritional content, by the identification of genes underlying the respective desirable traits in crop improvement programs.
Evolutionary Biology
In evolutionary biology, genome sequencing provides insights into the evolutionary history and relationships among species. It helps study genetic diversity, population dynamics, and evolutionary adaptations in different organisms.
Conservation Biology
Genome sequencing assists in conservation biology by assessing genetic diversity, identifying endangered species, and developing strategies for species preservation and management. It plays a vital role in conservation efforts aimed at maintaining biodiversity.
Conclusion
The Genome India Project thus forms a milestone in the scientific journey of India, hence it promises a leap in advanced health care, agriculture, and evolutionary studies. It makes the understanding of the implication of this project very relevant to you as a future policymaker for you to harness the potential of this project for national development. Welcome this knowledge to drive innovation; be sure of a healthier, prosperous India now and for generations to come.
