Finding resources when you or someone you love has a rare condition shouldn't feel like a research project. This page maps the landscape — patient communities, AI tools that speed up diagnosis, registries that turn your experience into data researchers can actually use, and quick-reference guides for specific conditions. Start wherever you are.
Not sure where to begin? If you're newly diagnosed or still searching for answers, start with Community & Support. If you've had genetic testing and want to understand your results, jump to AI Diagnostic Tools. If you want to contribute to research, see Research Organizations. For links specific to FOP, NGLY1 deficiency, or Niemann-Pick Type C, check Condition Quick Reference.
Community & Support
The most important resource for most people isn't a clinical trial or a database — it's finding someone else who understands. These communities and organizations connect patients, caregivers, and families across rare conditions worldwide.
Rare conditions touch every stage of life — and every kind of body.
NORD — National Organization for Rare Disorders
The largest rare disease patient advocacy organization in North America. Provides disease information, connects patients to support groups, and runs patient assistance programs for hundreds of conditions.
EURORDIS — Rare Diseases Europe
A patient-driven alliance of over 1,000 rare disease organizations across 74 countries. Advocates for European policy, coordinates European Reference Networks, and runs RareConnect — an international patient community platform.
Canadian Organization for Rare Disorders (CORD)
Canada's national network for people with rare disorders. Advocates for a national rare disease strategy, drug access, and diagnostic equity for Canadians living with conditions that the healthcare system often underserves.
RareConnect
Online communities organized by condition, hosted by EURORDIS and NORD. A place to find others living with the same rare condition — even when that community is small and scattered across continents.
Orphanet
The world's largest rare disease information portal. Search any rare condition to find its ORPHA code, expert centres, patient organizations, clinical trials, and registries — all in one place. Available in multiple languages.
Genetic Alliance
A network of over 10,000 organizations, companies, and government agencies working to advance genetics and genomics literacy. Supports families navigating genetic conditions with plain-language resources and community tools.
AI Diagnostic Tools
One of the hardest parts of living with a rare condition is getting a diagnosis in the first place. These tools don't replace doctors — they give clinicians a faster, broader starting point, and give patients the language to advocate for themselves.
Face2Gene
Facial recognitionUses facial recognition AI to match a patient's photo against known genetic syndrome profiles. Clinicians upload a photo and receive a ranked list of possible conditions. Has flagged rare syndromes in infants that were later confirmed through genetic testing — reducing diagnostic odysseys from years to days.
face2gene.com →TxGNN
Drug repurposingA graph neural network developed at Harvard that maps relationships between diseases, genes, and drugs across 17,000+ conditions. Identifies existing approved drugs that may be repurposed for rare conditions — critical when the patient population is too small for traditional drug development to target.
txgnn.org →Isabel DDx
Differential diagnosisA clinical decision support tool that generates a differential diagnosis list from symptom descriptions. Designed for clinicians, but helps rare disease patients prepare for appointments by understanding what conditions share their symptom profile.
isabelhealthcare.com →ClinVar + VarSome
Variant interpretationIf you've had genetic testing, these databases help interpret what your variants mean. ClinVar (NIH) classifies genetic variants by clinical significance. VarSome uses AI to aggregate evidence from multiple databases and provide plain-language variant summaries.
varsome.com →Undiagnosed Diseases Network
Diagnosis programA US-based NIH-funded network for patients who remain undiagnosed after extensive medical evaluation. Uses deep phenotyping, genome sequencing, and collaborative expert review across 12 clinical sites. Canadian equivalent: Care4Rare Canada.
undiagnosed.hms.harvard.edu →OMIM — Online Mendelian Inheritance in Man
Gene databaseThe authoritative database of genetic disorders and their associated genes. Updated daily by Johns Hopkins. Dense and clinical in tone, but the starting point for understanding any genetic condition's known molecular basis — and finding linked research.

Starting points for three conditions featured on this site. Each card gives you the essentials — what the condition is, who to connect with, and where to go next. For the science behind each condition, see the Research page.
Fibrodysplasia Ossificans Progressiva (FOP)
FOP causes soft tissues to gradually turn into bone, forming a second skeleton. The hallmark early sign is malformed big toes at birth. Palovarotene was approved in Canada in 2023 — the first targeted therapy for FOP. If you or a family member has FOP, connecting with the IFOPA community is the single most important first step.
NGLY1 Deficiency
NGLY1 deficiency prevents cells from properly dismantling misfolded proteins. The hallmark diagnostic clue is alacrima — inability to produce tears when crying. The Grace Science Foundation, founded by parents of the first diagnosed child, has become a model for patient-driven rare disease research.
Niemann-Pick Disease Type C (NPC)
NPC traps cholesterol inside lysosomes, progressively damaging neurons. Early signs include enlarged liver/spleen and jaundice. A characteristic later sign is vertical supranuclear gaze palsy — difficulty moving the eyes vertically. The NPC community has one of the strongest international patient registries among ultra-rare conditions.

Patient registries and research consortia are what turn individual rare disease experiences into data that researchers can actually use. Without them, conditions affecting fewer than a few hundred people worldwide have almost no evidence base.
These organizations fall into three tiers. Registry platforms collect structured longitudinal data directly from patients — the raw material for clinical trials and natural history studies. Research consortia conduct investigator-led studies, often using registry data. Policy and infrastructure organizations coordinate standards, advocacy, and cross-border data sharing.
If you have a rare condition, contributing to a registry is one of the most direct ways to advance research — even if you never participate in a clinical trial.
Full Comparison
How each organization contributes, what they're best used for, and when to consider them.
| # | Organization | Tier | What They Are | Best For | When to Consider |
|---|---|---|---|---|---|
| 01 | NORD IAMRARE | Registry | A structured registry system built to support longitudinal tracking and research-quality datasets for rare conditions. | Trial readiness, standardized data collection, participant dashboards, reminders, role-based access. | When you want to contribute to a condition-specific natural history study or help build the evidence base for future trials. |
| 02 | Genetic Alliance | Registry | Registry infrastructure with strong emphasis on participant governance, transparency, and consent controls. | Community-led registry building where patient control over data is the priority from day one. | When governance and participant data rights matter as much as data collection — particularly for communities wary of traditional research models. |
| 03 | Sanford CoRDS | Registry | A shared umbrella registry for rare disorders — a single home for diseases too small to sustain a standalone registry. | Low-barrier participation when patient numbers are extremely small and building a disease-specific platform isn't feasible yet. | When fewer than a few dozen known patients exist worldwide and immediate registry participation is more important than a condition-specific platform. |
| 04 | Care4Rare Canada | Research | An investigator-led national network focused on rare disease discovery, diagnosis, and clinical research across Canadian institutions. | Genetic discovery, research collaboration, and clinical integration through academic medical centres. | When a Canadian patient needs diagnostic support, genetic research collaboration, or connection to academic clinical pathways. |
| 05 | Orphanet | Policy | A European rare disease information system supporting disease coding, terminology standardization, and visibility across borders. | Standardized disease definitions, discoverability by researchers and clinicians, and cross-border interoperability. | When a condition needs to be formally classified and made discoverable to international researchers and healthcare systems. Not a registry host. |
| 06 | EURORDIS | Policy | A federation of over 1,000 patient organizations across 74 countries, driving EU-level policy and cross-border coordination. | Advocacy, policy influence, alignment with European Reference Networks, and international patient community building. | When European coordination, policy engagement, or access to the RareConnect patient community platform is the goal. |
Your experience is a resource too.
Every story on Bare Your Rare makes this community more visible — to researchers, to other patients, and to the people who've just been diagnosed and don't know where to start. You don't need a diagnosis. You don't need to be articulate about the science. You just need to be willing to share what it's actually like.
