Genome India Project is a national project funded by the Government of India's Department of Biotechnology and led by Centre for Brain Research (CBR) that aims to identify genetic variations in 10,000 representative individuals across India in the first phase of the study. Individuals from all over India are being recruited for the study based on their ethnicity, geographical location, and linguistic preferences. In this article, we will discuss in detail the Genome India Project which will help in UPSC exam preparation.

What is Genome?

• The human genome is the entire collection of deoxyribonucleic acid (DNA) found in the nucleus of every cell in the human body.
• It contains all of the genetic information necessary for the organism's development and functioning.
• DNA is a double-stranded molecule composed of four bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
• Every base on one strand matches a complementary base on the other (A with T and C with G).
• The genome is made up of approximately 3.05 billion such base pairs in total.
• On average, 0.1% of it differs between any two individuals.
• Individual genetic variations are critical for understanding disease predispositions, rare inherited disorders, drug response, and tracking migration and evolutionary patterns of population groups.

What is Genome Sequencing?

• While the sequence or order of base pairs in all humans is identical when compared to other species, there are differences in each human's genome that distinguishes them.
• Genome sequencing refers to the process of deciphering the order of base pairs in order to decode a human's genetic fingerprint.
• Genome sequencing, in other words, is the process of determining the complete DNA sequence of an organism's genome.
• The most common method of genome sequencing is known as next-generation sequencing (NGS).
• NGS enables the rapid, accurate, and low-cost sequencing of large amounts of DNA.

Application/Significance of Genome Sequencing

• Genome sequencing is used to evaluate rare disorders, pre-conditions for disorders, and even cancer from a genetic standpoint rather than as an organ disease.
• Prenatal screening has used gene sequencing to investigate genetic disorders/anomalies in foetuses.
• Crispr, a sequencing-based technology, has the potential to allow scientists to repair disease-causing mutations in genomes.
• Screening has been used to read virus codes. In 2014, a group of scientists sequenced Ebola samples from infected African patients to demonstrate how viral genomic data could reveal hidden pathways of transmission that could be halted, thus slowing or even preventing the spread of infection.
• The Covid-19 virus genome sequencing resulted in the development of a vaccine and the creation of diagnostic PCR machines.
  • The Indian SARS-COV-2 Genomics Consortia (INSACOG) was tasked with scanning coronavirus samples from patients, and it also put in place a sequencing framework. Sequencing was increased to track new variants as the virus evolved through mutations.

Human Genome Project

• Under the Human Genome Project, a group of scientists began working on determining the entire sequence of the human genome in 1990.
• In 2023, the project released the most recent version of the complete human genome, with a 0.3% error margin.
• The Human Genome Project enabled whole-genome sequencing, which now allows for the reading of an individual's genome to identify differences from the average human genome.
• These variations or mutations can reveal information about a person's susceptibility or future vulnerability to a disease, their reaction or sensitivity to a specific stimulus, and so on.

What is Genome India Project?

• It is a mission-mode, multi-institution consortium project, the first of its kind in India, supported by the Government of India's Department of Biotechnology.
• This project, supported by the Government of India's Department of Biotechnology, involves 20 national institutions from across the country.
• This project is led by the Centre for Brain Research at the Indian Institute of Science in Bengaluru, which serves as the central coordinator for a collaboration of 20 leading institutions, each of which collects samples and conducts its own research.
• The Indian Institute of Science (IISc) in Bengaluru, as well as several Indian Institutes of Technology (IITs), are among the institutions involved.
• Investigators in hospitals will lead data collection from participants via a simple blood test, and the information will be added to biobanks.
• The investigators have expertise in areas relevant to the project, such as human genetics, computational biology, big data research, statistics, and population genetics.
• This is a fantastic collaborative venture that promotes capacity building across several institutes throughout the country.
• It will also aid in the development of national capacity in high throughput genomic sequencing and computational analysis, including AI and ML.

Specific Aims for this Project

• Make an exhaustive list of genetic variations in Indians (common, low frequency, rare, single nucleotide polymorphisms or SNPs, and structural variations).
• Make an Indian reference haplotype structure. This reference panel can be used in future GWA studies to fill in missing genetic variation.
• Create low-cost genome-wide arrays for research and diagnostics.
• Create a biobank to store DNA and plasma samples for future research.

Need for Genome India Project

• The genetic makeup and environmental influences of populations around the world vary.
• As a result, it is critical to investigate the risk factors for complex genetic diseases and rare genetic variations that contribute to specific disorders in population-based studies.
• The Indian population of 1.3 billion people is made up of over 4600 population groups, several thousand of which are endogamous.
• These factors have contributed to the current Indian population's genetic diversity.
• As a result, the Indian population has distinct variations, and many disease-causing mutations are frequently amplified within some of these groups.
• As a result, findings from other populations' population-based or disease-based human genetics research cannot be extrapolated to Indians.
• As a result, the Genome India project is complex, but it is critical for understanding our country's genetic makeup.

Significance of Genome India Project

• Cataloguing Genetic Variation in Indians is a Pan-India initiative that focuses on Whole Genome Sequencing of representative populations across the country.
• The goal is to start with whole genome sequencing and then analyse data from 10,000 people representing the country's diverse population.
• This will aid in the development of an exhaustive catalogue of genetic variations in the Indian population, as well as the design of a genome-wide association chip for the Indian population, allowing for more cost-effective large-scale genetic studies.
• Furthermore, it would open new doors for the country's personalised medicine regimen, paving the way for predicting health and disease outcomes and modulating treatment protocols based on genome sequences.
• Furthermore, in its second phase, it would aid in identifying population groups that are more vulnerable to various risk factors for certain diseases, and would thus be useful in designing appropriate intervention strategies for such population groups.

Conclusion

The project's outcomes would be a valuable national resource for the country. They will help researchers all over India conduct large-scale human genetic studies in the future. The database of harmonised genetic variants will aid global variant interpretation efforts and will most likely serve as the foundational resource for next-generation basic and clinical research in India. Overall, this will be transformative for the country's healthcare scenario in the long run. However, the various risks and issues associated with gene mapping, storing, and using genetic data must be addressed, and a clear policy must be developed to ensure that this novel technology is used effectively.
