Why this matters
For the 5% of the global population affected by rare diseases, getting an accurate diagnosis often takes nearly a decade of exhausting tests. This AI breakthrough cuts that timeline down to a fraction, opening the door to faster treatments and ending years of medical uncertainty.
Key points
- Hebrew University researchers developed an AI tool, EvORanker, to diagnose rare genetic diseases.
- The AI analyzes gene evolution across more than 1,000 species to find hidden functional relationships.
- In clinical tests, it identified the correct disease-causing gene as the top candidate 70% of the time.
- The tool successfully diagnosed a child with a complex neurodevelopmental disorder after conventional tests failed.
- Researchers are now exploring how the technology could be applied to understand tumor regression in cancer.
For families of children with rare genetic disorders, the search for answers is often a grueling marathon. Known in the medical community as the "diagnostic odyssey," this journey can stretch for nearly a decade, characterized by endless testing, misdiagnoses, and profound uncertainty. Even with the advent of advanced genetic sequencing, a vast majority of these patients remain undiagnosed, leaving clinicians without a clear path for treatment.[1][3]
Now, a newly developed artificial intelligence tool is poised to radically shorten that timeline. Researchers at the Hebrew University of Jerusalem have introduced EvORanker, an AI algorithm designed to sift through thousands of genetic possibilities and pinpoint the exact mutation responsible for a patient's symptoms. The breakthrough, recently detailed in the journal Genetics in Medicine, represents a major leap forward in how computational biology can be applied to human health.[1][2][4]
What sets EvORanker apart from conventional diagnostic software is its foundational dataset. Traditional tools rely heavily on existing medical literature and known human genetic databases. If a gene has never been linked to a disease in a published study, standard algorithms will likely miss it. EvORanker, however, looks across the entire spectrum of evolution.[1][4]
Led by Dr. Christina Canavati and Professor Yuval Tabach, the research team built the AI to analyze how genes have evolved across more than 1,000 different species. The system operates on a well-supported biological principle: genes that evolve together often function together. By detecting these hidden patterns of co-evolution—a technique known as phylogenetic profiling—the algorithm can uncover functional relationships between genes that science has never explicitly linked to human disease before.[1][3][5]

The clinical results have been striking. In rigorous testing, EvORanker identified the correct disease-causing gene as its absolute top candidate in nearly 70 percent of cases. In 95 percent of the cases, the culprit gene was placed within the top five candidates. This performance significantly outpaces existing diagnostic tools, particularly in complex scenarios involving poorly understood or entirely novel genetic variants.[1][4][5]
In rigorous testing, EvORanker identified the correct disease-causing gene as its absolute top candidate in nearly 70 percent of cases.
Beyond the impressive statistics, the tool is already changing lives. The study highlighted a case involving a child with a complex, undiagnosed neurodevelopmental disorder. After conventional diagnostics had completely failed, researchers ran the patient's data through EvORanker. The AI identified a previously unrecognized gene as the likely cause, finally providing the family with an answer and giving doctors a target for potential therapeutic strategies.[1][4]
In another instance, the algorithm successfully revealed the genetic basis of a severe multisystem disease affecting multiple organs. By identifying biallelic variants in the SUPT4H1 gene, the tool helped clinicians understand that the disorder was tied to disrupted transcription processes. This level of clarity is crucial, as identifying the exact mechanism of a disease is the first necessary step toward developing a targeted treatment.[2][6]

The implications of this technology extend far beyond initial diagnoses. By uncovering new disease-causing genes, EvORanker can help researchers identify existing, FDA-approved drugs that might be repurposed to treat these rare conditions. This shortcut could save years of pharmaceutical development time, bringing effective therapies to patients much faster than the traditional drug discovery pipeline allows.[1][3][4]
While rare diseases are the immediate focus—affecting up to 5 percent of the global population and up to 8 percent in certain communities in Israel—the research team is already looking ahead. They are currently exploring how the EvORanker technology can be applied to oncology. Specifically, researchers hope to use the algorithm to understand why some tumors unexpectedly regress, potentially unlocking new mechanisms for treating stage 4 cancer.[1][5]

Viewpoints in depth
Medical Geneticists
Clinicians view the tool as a critical shortcut to ending the agonizing 'diagnostic odyssey' for patients.
For doctors on the front lines of rare disease treatment, the primary value of EvORanker is time. Traditional genetic sequencing often returns a massive list of 'variants of unknown significance,' leaving doctors to guess which mutation is actually causing the symptoms. By reliably ranking the true culprit in the top five candidates, clinicians can bypass years of trial-and-error testing, provide immediate psychological relief to families, and pivot directly toward finding a targeted therapy or repurposing an existing drug.
Computational Biologists
Researchers emphasize the paradigm shift of using evolutionary history rather than just human medical literature.
Computational scientists highlight that EvORanker overcomes the inherent bias in modern medicine: we only know what we have already studied. Standard AI tools are trained on existing human clinical data, meaning they struggle with entirely novel mutations. By leveraging phylogenetic profiling—analyzing how genes have co-evolved across more than 1,000 species over millions of years—biologists can infer a gene's function and its relationship to disease even if it has never been documented in a human patient before.
What we don't know
- It is not yet clear how quickly hospitals and clinics globally will integrate EvORanker into their standard diagnostic workflows.
- While the tool identifies the genetic cause, finding or developing an effective treatment for the newly discovered mutation remains a separate, complex challenge.
- The full efficacy of the algorithm in oncology applications, such as predicting tumor regression, is still undergoing early-stage research.
Key terms
- Diagnostic Odyssey
- The long, often years-long journey that patients with rare diseases undergo, involving numerous tests and misdiagnoses before finding the true cause of their symptoms.
- Phylogenetic Profiling
- A computational technique that predicts the function of a gene by analyzing its evolutionary presence or absence across different species.
- Biallelic Variants
- Mutations that occur on both copies of a specific gene (one inherited from each parent), often required to trigger certain recessive genetic disorders.
- Drug Repurposing
- The process of discovering new uses for already approved medications, which is much faster and cheaper than developing a new drug from scratch.
Frequently asked
How does EvORanker differ from standard genetic testing?
Standard testing looks for known mutations documented in medical literature. EvORanker uses AI to compare a patient's genes against the evolutionary history of over 1,000 species, allowing it to identify disease-causing genes that have never been seen before.
Is this tool available for patients now?
Yes, the researchers have made EvORanker accessible to clinicians and researchers, though patients will need their medical providers to run their genetic sequencing data through the system.
Can this AI cure rare diseases?
No, EvORanker is a diagnostic tool. However, by identifying the exact genetic cause, it allows doctors to search for targeted treatments or repurpose existing drugs much faster.
