Genetics and computer science: Navigating the legal and ethical challenges

The fusion of genetics and computer science is transforming how we understand and manipulate genetic data. By leveraging computational methods, we can decode the building blocks of life, predict biological functions, and design innovative genetic solutions. However, the rise of this field introduces complex legal, ethical, and regulatory challenges. This article explores the multifaceted relationship between genetics, computer science, and the law, highlighting key areas such as data protection, intellectual property, liability, and ethical considerations.

Genetics as data: Computational foundations

Genetics as a massive dataset

At its core, genetics represents a massive dataset encoded in a biological language of A, T, G, and C—shorthand for the following nucleotide bases:

• Adenine,
• Thymine,
• Guanine, and
• Cytosine.

These nucleotide bases form the chemical building blocks of DNA and RNA.

This language encodes instructions for life, dictating the structure and function of proteins, regulating cellular processes, and inheriting traits across generations. However, interpreting this intricate code requires more than biological expertise; it demands the power of computer science to manage its scale, complexity, and dynamic nature.

The scale and diversity of genetic data

Genetic datasets are not only vast but also diverse, encompassing:

1. entire genomes (the complete set of instructions for building and running a living organism);
2. transcriptomes (a snapshot of all the genes being used in a cell at a given time); and
3. epigenetic modifications (switches or markers on DNA that control which genes are turned on or off).

The sequencing of even a single genome involves billions of data points, far exceeding what can be analysed manually. Computer science steps in by providing advanced tools and algorithms to store, retrieve, and interpret this data efficiently. From compression techniques that reduce the size of raw sequencing data to cloud storage solutions that enable global access, computational systems form the backbone of modern genomics.

Enabling complex analyses

Beyond storage, computer science unlocks the potential of genetic data by enabling complex analyses. For example, algorithms for sequence alignment compare DNA sequences to identify similarities, pinpoint mutations, and infer evolutionary relationships. Machine learning models further elevate this analysis by predicting the function of genes, modelling gene expression patterns, and identifying disease-associated mutations with unprecedented accuracy.

Predicting protein structures

These computational capabilities also play a critical role in understanding the structure and behaviour of proteins, which are the functional products of genes. Predictive models like AlphaFold, powered by deep learning, have revolutionised protein structure prediction, making it possible to visualise the three-dimensional folding of proteins directly from genetic sequences. This has profound implications for drug discovery, as it enables the identification of potential therapeutic targets at a molecular level.

Exploring evolutionary relationships

Additionally, computer science aids in exploring evolutionary relationships by analysing genetic variations across species and populations. Phylogenetic algorithms (tools used to build family trees for species or genes) reconstruct evolutionary trees, offering insights into how organisms are related and how traits have evolved over time. These analyses enrich our understanding of biology and have practical applications, such as tracking the evolution of pathogens like viruses to inform public health strategies.

From data to actionable insights

In essence, computer science transforms the static information encoded in genetic sequences into dynamic, actionable insights. By bridging the gap between raw data and meaningful biological understanding, it empowers researchers to delve deeper into the mysteries of life, paving the way for breakthroughs in medicine, agriculture, and beyond. This interdisciplinary synergy is essential to address the complexities of genetic data and unlock its full potential for scientific and societal advancement.

Key applications

Sequence alignment

Sequence alignment is a fundamental tool in computational genetics, enabling the comparison of genetic sequences to uncover similarities and differences. Algorithms like BLAST (Basic Local Alignment Search Tool) quickly and efficiently compare a query sequence against a database of known sequences to identify regions of similarity. This can reveal shared ancestry, functional relationships, or mutations.

For instance:

• Tracing evolutionary paths: By aligning the genomes of different species, researchers can reconstruct evolutionary relationships and identify conserved genes critical for survival.
• Detecting mutations: In medical genetics, sequence alignment helps identify variations linked to diseases, such as single nucleotide polymorphisms (SNPs) or insertions/deletions that disrupt normal gene function.

Advanced alignment tools now incorporate machine learning to handle large datasets and improve accuracy, making sequence alignment a cornerstone of genomics research and diagnostics.

Genome assembly

Genome assembly involves piecing together short DNA fragments into a complete genome, much like solving a massive jigsaw puzzle. Tools like De Bruijn graphs use overlapping sequences to construct these fragments into a continuous sequence, even when faced with the challenge of repetitive regions in DNA.

Applications include:

• De novo genome assembly: Building genomes for newly sequenced species to understand their biology.
• Reassembly: Updating and refining genome sequences as better technologies emerge, such as assembling the first “gapless” human genome.
• Disease research: Assembling pathogen genomes (e.g., viruses and bacteria) to track outbreaks and design treatments.

Genome assembly is essential for advancing biodiversity studies, personalised medicine, and agricultural innovation.

Functional genomics

Functional genomics focuses on understanding how genes and regulatory elements contribute to biological processes. Machine learning models are revolutionising this field by predicting gene expression patterns and interactions.

Key applications include:

• Gene therapy: Machine learning helps identify the most effective genes to target for treating genetic disorders, such as designing vectors for delivering functional genes to replace defective ones.
• Understanding regulatory networks: By analysing RNA and protein interactions, functional genomics provides insights into how genes are turned on or off in response to environmental changes or diseases.
• Drug discovery: These methods are used to identify gene targets and predict the impact of drugs at a molecular level.

Functional genomics bridges the gap between DNA sequences and their real-world effects, making it indispensable for advancing precision medicine and understanding cellular processes.

High-performance computing and AI platforms

The sheer scale of genetic data requires the computational power of high-performance computing (HPC) and advanced AI platforms like TensorFlow and PyTorch. These technologies enable researchers to process and analyse vast datasets at speeds and accuracies that were previously unattainable.

Variant calling

Tools like DeepVariant, developed by Google, use deep learning to identify genetic variants from sequencing data with remarkable precision. This is critical for:

• Detecting mutations that drive diseases like cancer.
• Analysing rare genetic disorders.
• Personalising treatments based on a patient’s unique genetic profile.

Protein structure prediction

AI platforms like AlphaFold have revolutionised biology by accurately predicting the 3D structure of proteins from their amino acid sequences. Protein structure is essential for understanding how proteins work and how they can be targeted in drug development.

Applications include:

• Drug discovery: Identifying potential drug targets by modelling interactions between proteins and small molecules.
• Understanding diseases: Investigating how mutations affect protein folding and function, leading to conditions like Alzheimer’s or cystic fibrosis.
• Synthetic biology: Designing custom proteins with desired functions for industrial or medical use.

By combining HPC with AI, researchers can tackle previously insurmountable challenges in genomics, from deciphering complex diseases to designing innovative therapies. These tools are at the heart of the next wave of breakthroughs in genetics and biotechnology.

Data protection and privacy

Genetic data is sensitive and uniquely personal, raising significant privacy concerns. Regulatory frameworks worldwide seek to address these challenges:

Key regulations

1. General Data Protection Regulation (GDPR): In the EU, genetic data is classified as “special category data,” requiring explicit consent for processing.
2. Health Insurance Portability and Accountability Act (HIPAA): In the US, HIPAA protects genetic information when managed by healthcare entities.
3. Protection of Personal Information Act (POPIA): ZA’s POPIA aligns with global standards to safeguard genetic data.

Case study: 23andMe

A leading direct-to-consumer genetic testing company, 23andMe faced criticism for sharing anonymised genetic data with pharmaceutical companies for research. While this data-sharing model aligns with industry norms, it raised questions about the sufficiency of consumer consent and the ethical implications of secondary data use.

Intellectual property in genetics

The interplay of genetics and computer science creates unique intellectual property challenges.

Case study: CRISPR patent disputes

The Broad Institute and UC Berkeley have engaged in lengthy legal battles over patents for CRISPR-Cas9 gene-editing technology. The disputes revolve around who first invented and applied the technology in eukaryotic cells. This case underscores the complexity of protecting cutting-edge genetic innovations.

Liability and risk

With genetics-driven innovations come significant legal risks:

Case study: Golden State Killer investigation

Law enforcement used publicly available genetic databases to identify the Golden State Killer. While this marked a major investigative breakthrough, it raised ethical and legal questions about the use of genetic data submitted for non-criminal purposes, such as genealogy.

Algorithmic bias

AI models in genetics can reflect biases in training data, leading to errors or discriminatory outcomes. For instance, a genetic risk prediction model trained on data predominantly from European populations may produce less accurate results for individuals of other ancestries.

Ethical and regulatory compliance

Ethical principles underpin the legal frameworks governing genetics, emphasising autonomy, justice, and non-maleficence.

Case study: Havasupai Tribe versus Arizona State University

Researchers collected genetic samples from the Havasupai Tribe to study diabetes but later used the data for unrelated research on schizophrenia and population migration. This violation of consent sparked legal and ethical debates, leading to a settlement and the return of the genetic samples.

Emerging legal challenges

Case study: Myriad Genetics

Myriad Genetics once held patents on the BRCA1 and BRCA2 genes linked to breast and ovarian cancer. In Association for Molecular Pathology v. Myriad Genetics (2013), the US Supreme Court invalidated the patents, ruling that naturally occurring DNA sequences are not patentable. This case has shaped global IP laws concerning genetic data.

Emerging areas

• Data ownership: With biobanks growing in prominence, questions about ownership and participant rights have come to the fore.
• Gene editing: CRISPR’s use in germline modifications raises questions about regulation and accountability for long-term effects.
