The delicate balance between scientific progress and individual rights hangs in every drop of blood, every strand of DNA stored in India's biobanks.
Imagine being asked to donate your genetic material for research, with only a vague understanding of how this deeply personal information might be used years from now. This is the reality for participants in India's growing biobanking ecosystem—a network of repositories storing biological samples for research. As India positions itself as a global leader in precision medicine through initiatives like the Genome India Project, the critical question of informed consent faces significant impediments, from regulatory gaps to cultural and linguistic diversity. The journey from sample collection to breakthrough discovery hinges on addressing these challenges to build a foundation of trust between science and society.
Often described as "biological libraries," biobanks are organized collections of human biological materials—such as blood, DNA, tissues, and cells—stored alongside associated personal and health information for research purposes . Unlike traditional research that analyzes immediate samples, biobanks preserve these precious resources for future studies, many of which haven't even been conceived yet 2 .
India currently has 19 registered biobanks across the country hosting various biological specimens, including cancer cell lines and tissues 5 .
The strategic importance of biobanks has never been greater. They form the backbone of precision medicine—an approach that customizes healthcare based on individual genetics, environment, and lifestyle 6 . For a genetically diverse country like India, with its unique population structure shaped by practices like consanguineous marriages and endogamy (marrying within one's caste), biobanks offer unprecedented opportunities to develop targeted therapies for both common and rare diseases 4 5 .
Completed sequencing of 10,000 genomes from 99 ethnic groups to identify treatments for rare genetic diseases 7 .
Collected 10,000 samples to create better prediction models for cardio-metabolic diseases 5 .
Despite this progress, the ethical framework governing these repositories remains fragmented, with informed consent presenting perhaps the most complex challenge.
Informed consent represents the ethical cornerstone of all research involving human participants. In traditional research settings, participants consent to a specific study with clearly defined parameters. Biobanking, however, introduces unique complications because samples are often collected without knowing their future research applications 2 .
India currently lacks comprehensive legislation specifically governing biobanks 2 . Instead, the field is primarily guided by non-binding ethical guidelines, most notably the Indian Council of Medical Research's (ICMR) National Ethical Guidelines for Biomedical and Health Research Involving Human Participants from 2017 2 3 . While these guidelines define biobanks and set standards for donor consent, they lack enforceable legal status and fail to comprehensively address specific data protection concerns 2 3 .
The profound implications of inadequate consent processes were starkly illustrated in the Havasupai tribe case—a landmark example of consent failure in genetic research 4 .
Between 1990 and 1994, researchers from Arizona State University collected DNA samples from approximately 400 members of the Havasupai tribe to study type-II diabetes, which had high prevalence in their community 4 .
Years later, a tribe member discovered their genetic data had been used for studies on schizophrenia, migration patterns, and inbreeding—none of which had been mentioned during the consent process 4 .

Court rules in favor of the Havasupai, awarding compensation and ordering return of all DNA samples.
India's remarkable diversity presents unique challenges for meaningful consent. With dozens of languages and countless cultural variations, obtaining truly informed consent requires more than simple translation 4 . Genetic concepts must be explained in culturally appropriate terms, and consent processes must respect varying community norms and values 4 .
The Havasupai case underscores what happens when this isn't done properly—consent was obtained in English, a second language for the tribe, raising questions about its validity 4 .
The DPDPA's broad exemption for research purposes creates uncertainty about adequate privacy safeguards for biobank participants 3 . Different approaches to data confidentiality further complicate the consent landscape:
The question of data ownership remains particularly contentious—should rights to stored samples and derived data lie with donors, researchers, or institutions? This lack of clarity becomes especially problematic when commercialization is involved .
Biobanking increasingly intersects with commercial applications, particularly in pharmaceuticals and biotechnology 2 . Participants may consent to research without understanding that their samples could contribute to commercial products from which they won't benefit financially .
This raises critical questions about equitable benefit-sharing, especially when research draws from vulnerable or marginalized populations .
For indigenous and marginalized groups, community-driven governance offers a promising way forward 4 . The CARE Principles (Collective Benefit, Authority to Control, Responsibility, and Ethics) provide a framework for ensuring respect for cultural values and data sovereignty 4 .
India has an opportunity to develop comprehensive biobanking legislation that balances research needs with participant rights . Such legislation should include:
| Research Reagent/Material | Primary Function | Application in Genetic Research |
|---|---|---|
| Biological Samples (blood, DNA, tissues, cells) | Source of genetic material and biological data | Foundation for genomic sequencing and analysis |
| Storage Media & Cryopreservatives | Maintain sample integrity during long-term storage | Enables preservation of biological samples in biobanks for future research |
| DNA/RNA Extraction Kits | Isolate pure genetic material from samples | Essential step for preparing samples for genetic analysis |
| PCR Reagents & Enzymes | Amplify specific DNA sequences | Allows researchers to study tiny amounts of genetic material |
| Genomic Sequencing Kits | Decode the complete DNA sequence | Used in projects like Genome India to map genetic variations |
| Cell Culture Materials | Grow and maintain living cells in laboratory | Supports creation of patient-derived organoids for drug testing |
The impediments to informed consent in India's genetic research and biobanking landscape are significant—spanning regulatory gaps, cultural complexities, and ethical ambiguities. Yet, addressing these challenges is not merely about avoiding harm; it is about building the public trust necessary for sustainable scientific progress.
As India stands at the forefront of the precision medicine revolution, the choices made today about consent, privacy, and community engagement will reverberate for generations.
By developing culturally responsive governance, enacting robust legislation, and prioritizing participant rights, India can not only advance its own healthcare outcomes but also establish a globally recognized model for ethical biobanking that respects both scientific innovation and human dignity.
The promise of genetic medicine for all Indians depends on a simple but profound foundation: every sample given, every consent form signed, must represent a relationship of transparency, respect, and shared purpose between science and society.
