News: 10,000 Indian genomes to be sequenced by year-end

 

What's in the news?

       The Genome India Project, a Centre-backed initiative to sequence 10,000 Indian human genomes and create a database, is about two-thirds through, said Rajesh Gokhale, Secretary, Department of Biotechnology (DBT).

 

Key takeaways:

       India has sequenced close to 7,000 genomes and 3,000 of these are already available for public access by researchers. 

       The mission expects the 10,000 genomes to be completely sequenced by the end of the year.

       About 20 institutions across India are involved in the project though the analysis and coordination is done out of the Centre for Brain Research, Indian Institute of Science (IISc), Bangalore.

 

 

 

Genetic diversity in India:

       The Indian population of 1.3 billion consists of over 4,600 population groups, and many of them are endogamous. These factors have contributed to the genetic diversity of the current population.

       Thus, the Indian population harbours distinct variations and often many disease-causing mutations are amplified within some of these groups.

 

Genome India Project:

       India’s Genome Project is a government-funded project to sequence more than a thousand individuals from diverse ethnicities to create a genome database for India.

       It is a Central Sector Project.

 

Aim:

       The GIP aims to collect 10,000 genetic samples from citizens across India, to build a reference genome.

       The genome contains all the genetic matter in an organism, i.e., the complete set of DNAs.

 

Goal:

       The goal of the research is to develop predictive diagnostic indicators for several high-priority diseases and other uncommon and genetic disorders.

       In phase 2, the project would collect genetic samples from patients with three broad categories – cardiovascular diseases, mental illness, and cancer.

       Through whole-genome sequencing, the plan is to build an exhaustive catalogue of genetic variations for the Indian population.

 

Nodal agency:

       Department of Biotechnology (DBT), Ministry of Science and Technology.

 

Targeted areas:

       Some of the priority areas are Precision health, Rare genetic disorders, Mutation spectrum of genetic and complex diseases in the Indian population, Genetic Epidemiology of Multifactorial Lifestyle Diseases, and Translational Research.

 

Significance:

1. Predictive diagnostic markers:

       GIP will aid our understanding of the nature of diseases affecting the Indian population, and then ultimately support the development of predictive diagnostic markers.

       Human genome sequencing is important to establish a link between diseases and the unique genetic make-up of each individual.

2. Information on human species:

       Global science would also benefit from a mapping project, which would provide data useful for the mapping of the spread and migration of a range of life forms in the old World and thus would help in better understanding of human evolution.

       It would aid in the designing of genome-wide association chips which will facilitate further large-scale genetic studies in a cost-effective manner.

3. Next-Generation personalized medicine:

       It would also open new vistas for advancing next-generation personalized medicine in the country, paving the way for predicting health and disease outcomes and modulating treatment protocols based on the genome sequences of the patients.

4. Targeted preventive care:

       The initiative would also support the development of targeted preventive care, as it has the potential to help identify those population groups which are more susceptible to various risk factors for certain diseases.

       For instance, if a region shows a tendency towards a specific disease, customized interventions can be made in the region, accordingly, leading to more effective treatment overall.

5. Precision medicine:

       The initiative reflects India’s progress in gene therapies and precision medicine, and its movement towards emerging next-generation medicine which yields the possibilities for greater customization, safety, and earlier detection.

 

Challenges ahead:

1. Privacy issues:

       The volume of information contained in a genome sequence is vast. Policies and security measures to maintain the privacy and safety of this information are still new.

       The Indian Council of Medical Research, the apex body that regulates clinical trials in India, has no specific guidelines to govern genetic testing laboratories.

2. Chances of racial discrimination:

       The question of heredity and racial purity has obsessed civilizations, and more scientific studies of genes and classifying them could reinforce stereotypes and allow for politics and history to acquire a racial twist.

3. Ethical issues:

       The introduction of whole genome sequencing may have ethical implications. Genetic testing has potential downsides such as genetic discrimination, loss of anonymity, and psychological impacts.

4. Misuse of data:

       Companies have access to sensitive personal information, which could be hacked or sold to third parties without participant's consent. India is yet to pass a Data Privacy Bill with adequate safeguards.

5. Accuracy:

       How accurately and reliably genome sequencing measures genome variants is a big challenge.

 

WAY FORWARD:

1. Training:

       It is important to train more clinicians for gene data interpretation and rope in more labs for sequencing. Training more physicians to study medical genetics for speedier analysis is needed.

2. Data security:

       Given the sensitivity of genomic data, every effort must be made to minimize the likelihood of data breaches and to maintain public trust in institutions that gather, store and use such data.

       A practical and feasible solution to build such a reliable and safe database is the application of blockchain technology to secure genomic data.

3. Effective policy:

       There is a need for a comprehensive and effective policy to guide the use of genomic information, with significant emphasis on protecting the privacy of research subjects.

       One way to make this possible is through ‘dynamic consent’ by which people who wish to participate in a research project can register themselves and provide consent on an ongoing basis.

4. Collaborative effort:

       A collaborative and harmonized effort is needed to balance sharing of genomic data with an individual's privacy.

       A framework must be designed transparent enough to specify the purpose of the collected genomic data and the duration for which it will be stored in the database.

 

Thus, the Genome India Project reflects India’s progress in gene therapies and precision medicine, and its movement towards emerging next-generation medicine which yields the possibilities for greater customization, safety, and earlier detection.
