DeepMind’s development of Enformer and the implications of AI-based gene sequencing
According to Marktechpost: DeepMind, in collaboration with their Alphabet colleagues at Calico, [introduced] Enformer, a neural network architecture that accurately predicts gene expression from DNA sequences.
Earlier studies on gene expression used convolutional neural networks as key building blocks. However, their accuracy and usefulness have been hampered by problems in modeling the influence of distal enhancers on gene expression. The proposed new method is based on Basenji2, a program that can predict regulatory activity from DNA sequences of up to 40,000 base pairs.
The team expressed a need for a fundamental architectural modification to capture extended sequences and understand whether the regulatory DNA elements influence expression at greater distances.
The new model is based on Transformers to leverage self-attention processes to absorb considerably more DNA background. The Transformers are built to “read” substantially expanded DNA sequences because they are suitable for looking at long text sections. The model architecture can describe the influence of critical regulatory regions called enhancers on gene expression from further away within the DNA sequence. It does this by successfully processing sequences to consider interactions at distances greater than five times (i.e., 200,000 base pairs) than earlier methods.
Although it is now feasible to analyze an organism’s DNA, understanding the genome requires complex studies. Despite extensive research, the vast majority of DNA regulation of gene expression remains a mystery. Enformer recognizes the vocabulary of the DNA sequence in part, similar to a spell checker, and may thus indicate modifications that potentially change gene expression.
The primary purpose of this new approach is to forecast which changes to the DNA letters, commonly known as genetic variations, would affect the gene’s expression. Enformer outperforms earlier models in predicting the impact of genetic variants on gene expression, both in natural genetic variants and synthetic variants that change critical regulatory regions. This characteristic helps decipher the expanding number of disease-associated variations discovered in genome-wide association studies.
Enformer is a significant step forward in complex genomic sequence studies. The team intends to collaborate with other researchers and organizations interested in using computational models to answer the big problems in genomics.

Ethical Issues Regarding CRISPR Mediated Genome Editing
CRISPR-Cas9 is a powerful genome editing technology that allows scientists to modify DNA with a high degree of precision. While it holds immense promise for various applications, including medical research, agriculture, and biotechnology, there are several ethical issues associated with its use. Some of the key ethical concerns include:
- Off-Target Effects: CRISPR-Cas9 editing is not always perfectly accurate and can inadvertently introduce changes in unintended locations within the genome, known as off-target effects. This could lead to unintended consequences, such as causing new diseases or disrupting essential genes. Ensuring the accuracy and specificity of CRISPR edits is crucial to avoid these potential risks.
- Germline Editing: One of the most debated ethical issues is the editing of human germline cells (sperm, eggs, embryos) to make heritable genetic changes. Altering germline cells could affect not only the individual being edited but also future generations. There are concerns about unforeseen genetic and health implications, as well as the potential for designer babies and the creation of genetic “haves” and “have-nots.”
- Informed Consent: When using CRISPR for medical purposes, obtaining informed consent from individuals or patients is crucial. However, explaining the potential long-term consequences and uncertainties associated with genome editing can be challenging, especially when dealing with complex scientific information.
- Unequal Access: As with many new technologies, there is a risk of unequal access to CRISPR-based therapies or enhancements. Ensuring that these technologies are available to all socio-economic groups is an ethical imperative to prevent exacerbating existing inequalities.
- Environmental Impact: In agriculture, CRISPR can be used to genetically modify crops and livestock for improved yield, disease resistance, and other traits. However, the environmental impact of releasing genetically modified organisms into ecosystems raises concerns about unintended consequences and potential disruption of ecosystems.
- Dual-Use Concerns: The same technologies that have positive applications can also be misused for harmful purposes. CRISPR has the potential for creating engineered organisms with harmful traits, posing risks such as bioterrorism and the accidental release of organisms with unintended ecological impacts.
- Long-Term Effects: Given the relative novelty of CRISPR technology, the long-term effects of genome editing on both individuals and ecosystems are not fully understood. There is a need for ongoing monitoring and research to ensure that any unintended consequences are identified and addressed.
- Regulation and Oversight: Establishing appropriate regulatory frameworks and oversight mechanisms for CRISPR research and applications is essential. Balancing innovation and safety requires careful consideration of ethical, legal, and societal concerns.
- Cultural and Religious Perspectives: Different cultural, religious, and philosophical beliefs may shape opinions on genome editing. Some may view editing the human germline as interfering with nature or as morally objectionable, while others may see it as a way to alleviate suffering.
- Transparency and Openness: Ethical concerns arise when there is a lack of transparency in the research process or when important information, such as negative results or unsuccessful experiments, is not shared. Openness in research is crucial for building trust and ensuring responsible development.
Addressing these ethical issues requires collaboration between scientists, policymakers, ethicists, and the public. Ethical considerations should guide the development, implementation, and regulation of CRISPR technology to maximize its benefits while minimizing potential risks and negative consequences.
