What if a computer could notice a pattern in a patient's medical history that had been difficult to recognize for years?
What if it could help a doctor compare thousands of genetic possibilities in a fraction of the time?
Or identify subtle patterns in medical images that might point towards a rare genetic condition?
These are some of the possibilities researchers are exploring with artificial intelligence (AI) in rare disease and genetic medicine.
Rare genetic disorders can be particularly difficult to recognize because they are uncommon, symptoms can vary widely and a single condition may affect several parts of the body. Even with advances in genetic testing, interpreting the large amount of information generated by modern sequencing remains challenging.
AI may become an important tool in this process.
But there is an important distinction:
AI may help doctors recognize patterns and prioritize possibilities. It does not replace the doctor, geneticist or genetic counsellor.
So, how could AI actually help?
What is AI in healthcare?
Artificial intelligence refers to computer systems designed to perform tasks that normally require aspects of human intelligence, such as recognizing patterns, processing information or making predictions.
In healthcare, AI can analyze very large amounts of information.
For example, an AI system may be trained to identify patterns in:
Medical records
Laboratory results
Medical images
Genetic data
Clinical symptoms
Patient histories
When these technologies are applied to genetic and rare diseases, the aim is often not to produce an instant diagnosis.
Instead, AI can help healthcare professionals find patterns, organize information and prioritize possible explanations.
Why could AI be useful for genetic disorders?
The human body can produce an enormous amount of medical information.
A patient may have hundreds of clinical observations, laboratory results and imaging findings. Genetic testing can add millions of pieces of information about DNA.
For a rare genetic disorder, only a small portion of that information may be relevant.
Finding the important clues can be like looking for a needle in a haystack.
AI and machine-learning systems can process large datasets rapidly and may help identify relationships that would be difficult to evaluate manually.
Researchers are therefore investigating AI across several parts of the rare disease diagnostic process. A 2025 review identified three major areas of interest: genetic analysis, imaging-based phenotyping and natural-language processing of clinical information.
1. AI can help recognize patterns in symptoms
Patients with genetic disorders may have combinations of symptoms that are individually common but unusual when considered together.
For example, a patient might have developmental differences, a particular neurological feature, a specific laboratory finding and certain physical characteristics.
A doctor may recognize the pattern based on experience.
AI systems can also be trained to look for relationships between clinical features and known genetic disorders.
This approach is sometimes called phenotype-driven analysis.
A phenotype simply means the observable characteristics or features of a person�including symptoms, physical findings and certain laboratory or imaging features.
Research has shown that machine-learning systems can use phenotype information to support the identification of possible rare disorders and, in some settings, help recommend appropriate genetic testing.
The potential benefit is particularly important when a condition is unfamiliar to the healthcare professional seeing the patient.
2. AI can assist with medical image analysis
Some genetic disorders are associated with recognizable physical characteristics.
This can include particular facial or skeletal features.
Researchers have developed computer-vision and facial-phenotyping approaches that analyze patterns in photographs or other clinical images and compare them with known disease patterns.
These technologies are sometimes referred to as next-generation phenotyping.
Studies have explored whether AI-based facial analysis can help distinguish between rare genetic syndromes, particularly when physical features are subtle or difficult to recognize.
This does not mean that a photograph can diagnose a genetic disease.
Rather, an AI tool may potentially identify a pattern that prompts a healthcare professional to consider certain conditions and decide whether further evaluation is appropriate.
3. AI can help analyze genetic information
Modern genetic testing can generate enormous amounts of data.
Whole-exome and whole-genome sequencing can identify many genetic variants, but not every variant is disease-causing.
Some variants are harmless. Others may contribute to disease. Some remain uncertain because there is not yet enough evidence to determine their significance.
This creates a major challenge:
Which genetic finding is actually relevant to this patient's condition?
AI and computational tools can help researchers and clinical teams prioritize and analyze genetic variants based on available evidence and the patient's clinical features.
Modern rare disease diagnosis increasingly combines genomic data with clinical information, and computational approaches are being developed to help with this interpretation.
4. AI can help make sense of medical records
Patients with rare diseases may have years of medical records.
Their information can be spread across different hospitals, specialists and reports.
Important clues may be buried in clinical notes.
AI technologies, including natural-language processing, can potentially extract relevant information from large amounts of unstructured medical text.
For example, an AI system could help identify recurring symptoms, previous diagnoses, laboratory findings or other features that may be relevant to a rare disease.
Researchers are actively studying these approaches as a way to improve the organization and interpretation of clinical information.
5. AI may help identify patients who need further evaluation
One of the most interesting possibilities is using AI as an early warning or decision-support tool.
Imagine a patient whose medical history contains several features associated with a genetic disorder.
The doctor may already be considering the condition.
An AI system could potentially flag the combination of features and suggest that further assessment or genetic evaluation may be worth considering.
This could be particularly useful for conditions that are difficult to recognize because they are rarely encountered in routine clinical practice.
Importantly, the final decision should remain with qualified healthcare professionals.
Could AI reduce the diagnostic odyssey?
Potentially�but we need to be realistic.
Patients with rare diseases can experience long diagnostic journeys because of symptom complexity, limited awareness and difficulty accessing appropriate diagnostic expertise.
AI may help shorten parts of this journey by:
Highlighting unusual combinations of symptoms
Suggesting possible diagnoses for clinical consideration
Helping prioritize genetic variants
Supporting selection of appropriate genetic tests
Organizing information from medical records
Identifying patterns in medical images
However, AI is not a magic shortcut to diagnosis.
A 2024 evidence review on genomic sequencing found that early genome sequencing can be useful in appropriate clinical settings, but evidence varies across patient groups and clinical contexts, and expert involvement remains important.
AI should be viewed as another tool within this broader diagnostic process.
What are the limitations of AI?
The possibilities are exciting, but there are important challenges.
AI needs good data
AI systems learn from data.
If the data used to develop an AI system are incomplete, unrepresentative or biased, the system may not perform equally well for everyone.
Rare diseases create a particular challenge because there may be relatively few patients with any individual condition.
This means that collecting sufficiently large and diverse datasets can be difficult.
AI can make mistakes
AI-generated suggestions are not automatically correct.
A system may identify a condition that appears to match the patient's features but is ultimately not the correct diagnosis.
This is why AI output needs to be reviewed by appropriately qualified healthcare professionals.
Some AI systems can be difficult to explain
Healthcare decisions require more than a prediction.
Doctors and patients may need to understand why a particular possibility was suggested.
Researchers are therefore placing increasing importance on transparency and explainability when developing AI systems for healthcare.
Privacy matters
Genetic information is particularly sensitive.
AI systems that process genetic or medical data must address important questions about privacy, security, consent and responsible data use.
Patients should understand how their information will be collected, stored and used when participating in AI-related research or healthcare programmes.
What about AI chatbots and online symptom checkers?
This is especially important for patients and caregivers.
It may be tempting to enter symptoms into an AI chatbot and ask:
�Do I have a genetic disease?�
AI tools can sometimes help explain medical terminology or organize questions for a doctor's appointment.
However, an online AI response should not be treated as a diagnosis.
Current research on large language models in rare disease diagnosis shows substantial variation in performance, and recent systematic evidence has highlighted the absence of prospective clinical validation for the evaluated systems.
In other words, an AI chatbot may be useful for learning�but it should not replace a clinical assessment or genetic evaluation.
AI and doctors: partners, not competitors
The most useful way to think about AI in rare disease diagnosis is not:
�Will AI replace doctors?�
A better question is:
�How can AI help doctors recognize patterns earlier and make better-informed decisions?�
A doctor brings clinical judgement, patient interaction, physical examination and an understanding of the patient's individual circumstances.
A genetic specialist brings expertise in genetic conditions and interpretation.
AI can potentially add another capability: rapid analysis of large amounts of information.
Together, these capabilities may eventually make rare disease diagnosis more efficient and precise.
What could the future look like?
Research in AI and genetic medicine is developing rapidly.
Future systems may increasingly combine several types of information�clinical symptoms, medical images, laboratory results and genomic data�to help healthcare professionals build a more complete picture of a patient's condition.
Researchers are also exploring ways to make AI systems more explainable, protect patient data and improve their performance when data are limited.
But there is still a significant gap between promising research and routine clinical use. Recent reviews emphasize that many AI approaches in rare diseases remain at the proof-of-concept or research stage and require stronger clinical validation before widespread implementation.
What does this mean for patients?
Patients do not need to become experts in AI or genetics.
The most important message is simple:
AI may become an additional tool that helps healthcare professionals recognize rare genetic disorders earlier�but it should not be treated as a replacement for medical evaluation.
If you or your child has persistent or unexplained symptoms, speak with a qualified healthcare professional.
If a genetic condition is suspected, your healthcare team may decide whether specialist assessment or genetic testing is appropriate.
And if AI is used as part of a healthcare or research programme, patients should have the opportunity to understand how it is being used and what role it plays in their care.
From data to earlier recognition
Rare disease diagnosis often involves connecting many small pieces of information.
One symptom may not provide the answer.
One genetic variant may not provide the answer.
One medical image may not provide the answer.
But when information from different sources is brought together, a meaningful pattern may emerge.
That is where AI has potential.
Its greatest value may not be in replacing human expertise, but in helping healthcare professionals see, organize and interpret information that might otherwise be difficult to connect.
For families who have spent years searching for an explanation, even earlier recognition can be meaningful.
At Healing Wings Foundation, we believe that innovation should ultimately serve people. AI, genomics and other emerging technologies hold promise for improving the rare disease journey�but they must be developed and used responsibly, with patient safety, privacy, clinical oversight and equity at the centre.
Technology can help find the clues. Human expertise must help turn those clues into responsible care.
