Googles AlphaGenome Cracks DNAs Code

AlphaGenome creates a new AI way to read large pieces of DNA, allowing researchers to determine mutations and their effects on how genes are utilized. AlphaGenome was first published in Nature on 28 January, and has outperformed 25 other genomic tools in determining how &ldquonon-coding&rdquo DNA &ndash or dark matter &ndash is responsible for the majority of diseases. This is not just another way to develop drugs, but rather a game-changing platform that will allow biotechnology and pharmaceutical investors and corporations, trying to capitalize on a genomic market of over 100B, to reduce the time and expense of the research and development process.

We have been able to obtain inexpensive genome sequences, however understanding how those sequences affect how organisms use DNA (Variants) has created a bottleneck. Generating multiple false-starts has cost the industry billions of dollars; AlphaGenome is about to change that forever.

How AlphaGenome Sees What Others Miss

This transformer-based architecture processes long sequences (1Mb each, 100x the length of previous approaches) and models what is thought to be all the human regulatory signals from chromatin function through gene splicing (5,930 signals).

Ziga Avsec, Staff Research Scientist at Google DeepMind, said that AlphaGenome acts as a "virtual genomics lab," that allows results of simulation experiments without the need of laboratory work. It has been trained on both human and mouse data and can therefore generalize its predictions to other vertebrate species — an important action for designing drugs for cross-kingdom applications.

Benchmark Domination: Numbers Don't Lie

Defeating all the best tools currently in use regarding splicing, chromatin characterization, and enhancer prediction, AlphaGenome's superior performance is demonstrated by QuASAR (+12% accuracy for splicing), Vishnu Enhancer Predictor (30% better prediction of transfer), and its ability to connect the molecular dots between diseases and patients, as demonstrated by Robert Goldstone of the Francis Crick Institute.

Significant advances have been noted in modelling by using AlphaGenome. The absence of the long-range context in AlphaFold prevents its application to 98% of the human genome, the portion of the genome where most cancers, diabetes, and most rare diseases reside.

Business Explosion: Pipeline Turbocharger

By 2030, genomics is projected to reach $100 billion; with AlphaGenome making multiple investments. Virtual testing of genetic variants reduces lab expenses by 40%, creating $2 billion of savings per drug candidate. Large pharmaceutical companies are creating models to predict patient responses to drugs before clinical trials; while CRISPR organizations will accelerate development by creating tissue-based genomic prediction models that optimise the use of a CRISPR system to transduce specific cell populations.

Real-World Wins: From Lab to Clinic

Early adopters of the Broad Institute will use it to examine cohorts of patients diagnosed with leukaemia to discover previously unknown causes of disease through genetic analyses not previously identified by genome-wide association studies (GWAS). Early-stage companies are establishing value-adding platforms through Series A rounds of thinning (typically $10 million). Hospitals are using it to enhance their capability to produce precision-care reports and charge an average of $5000 versus $50,000 for whole-genome sequencing.

From an ethical perspective, DeepMind will share its model weights with the public, thus democratising access to the application of those models while at the same time applying for patents on their applications.

Challenges

Performance Potential Amid Challenges

AlphaGenome is capable of passing performance evaluations and exhibits potential. Therefore, there are challenges related to clinical deployment that are associated with the use of AI.

Validation: The Primary Clinical Barrier

One of the biggest challenges that will impede the use of AlphaGenome in clinical settings is the lack of validation. The training data associated with AlphaGenome included a significantly higher number of European ancestry individuals relative to other various ancestries. This may cause bias within the genomic data, causing issues with the identification of mutations that are unique to South Asian or African patients.

As a result of the possible biases present in this data set, pharmaceutical companies have been forced to discontinue the use of the 23 and Me genomic testing platform, which revealed inconsistencies in ancestry identification for African and South Asian patients as well.

Costly Trials Required

Regulatory bodies have stipulated that genetic testing platforms such as AlphaGenome must complete prospective clinical trials in excess of 10,000 patients of various ancestries prior to entering into clinical implementation. The costs associated with completion of these clinical trials for AlphaGenome will likely run approximately $50 million and take 2-3 years to complete.

Black-Box Risks

The issues associated with the lack of explainability mean that the black-box nature of the predicted outcomes associated with the CRISPR modifications and liability for the outcomes of these CRISPR modifications are ambiguous.

Resource Barriers

The resources required to effectively train and utilize AlphaGenome will prohibit most start-up companies from utilizing the platform. AlphaGenome will require approximately 10,000 H100s at a cost of $100 million (via cloud computing) to achieve sufficient training and an estimated number of A-100s to perform the requisite inferences.

GDPR Consent Complications

The problems created by the issues related to GDPR authorizations (issues associated with consent) for patients who received genomic testing through 23 and Me will cause additional complications in the use of genomic data for the treatment of patients.

Nobel Trajectory Despite Hurdles

Despite the various issues with AlphaGenome that may delay or prevent clinical use in the future, AlphaGenome is the equivalent to AlphaFold 2.0 in that it will achieve its goal of winning a Nobel Prize.
