The RAO Synergies Tool provides information about both the disease and the organization representing the disease area. All information is straight from patient organizations themselves—and is intended to help rare disease patient organizations learn, share and collaborate.

This tool allows users to search for commonalities by using a wide variety of filters, including clinical, research, and organization features.

Each organization represented in the tool completed a questionnaire. Responses were gathered into a database, which feeds this tool. An example of the survey can be found here. Information will be updated annually.

Clinical Filters: these filters relate to the clinical aspects of rare disease

• Disease class
• Body systems
• Organs
• Genes
• Type of inheritance
• Disease Mechanism
• Age of onset
• Incidence
• Prevalence
• Populations and/or ancestry with higher prevalence
• Symptoms/Phenotypes
• Biomarkers
• Existing therapies, approved for the disease
• Existing therapies, approved for the symptoms
• Existing therapies, off-label
• Existing therapies, EAP
• Existing therapies, alternative
• Existing therapies, other

Organization and Research Filters: these filters relate to the rare disease organizations’ infrastructure as well as their research-enabling efforts

• Grant cohort
• Cell line, type
• Cell line (institution, location)
• Cell line, share
• Disease model
• Disease model (institution, location)
• Disease model, share
• Clinical trial (organizational role)
• Biobank (institution, location)
• Center of Excellence (institution, location)
• Natural History Study
• Data collected for natural history study
• Platform for natural history study
• Registry
• Data collected for registry
• Data entry for registry
• Platform for registry
• FDA Patient Listening Session
• FDA Patient Focused Drug Development (PFDD) Program
• ICD codes
• Diagnostic guidelines
• Clinical guidelines
• Organizational roles
• Scientific Advisory Board (SAB) policies and whether you share them
• Clinical Research Network (CRN) policies and whether you share them
• Research Roadmap and whether you share it
• International chapters: divisions of your organization in other countries
• International partners: separate organizations in other countries with which you partner

When you first arrive on the main page, you will see a list of participating organizations. On the left side is an expandable list of filters from which to choose. Within each filter, you can search or browse to make your selection. As you select filters, the list of organizations will change to reflect those that match the filters. Only items reported in the survey are included as options in the filters.

Selected filters will also display definitions or synonyms; for example, if you type “nosebleed” in the search, the filter will locate the symptom “epistaxis”. Any filter with a question mark symbol next to it has a definition available to view by clicking the question mark to open the definition. For genes, both the definition of the gene and a link to the expression of the gene in CZI’s CELLxGENE tool are included. Please note that by clicking this link, you will leave this website and enter the CELLxGENE website, which has its own privacy policy. You can view CELLxGENE’s privacy policy here.

Some of the responses to the questionnaire were codified in order to help users find more areas of synergy. For instance, in cell lines and disease models, we coded by type of cell or animal model, rather than the specific line, so users can more easily find organizations working with iPSCs or zebrafish. However, users can see the full free text responses from the questionnaire on each organization’s Detail Page.

The following sources were used for the filter definitions when possible and coding of responses when needed:

• Disease class: Orphanet
• Genes: Genecards
• Body systems: Wikipedia
• Types of inheritance: NHS Genomics Education, and NCBI: Understanding Genetics
• Symptoms: Human Phenotype Ontology and MedLine Plus
• Biomarkers: NCBI: Biomarkers definitions and their applications
• Cell Lines: EMBL-EBI Ontology Lookup Service

Currently, filters are combined using “AND” boolean logic; “OR” and “NOT” filters are not possible at this time. For example, if you filter by selecting a symptom or symptoms and an organ, the results will show you organizations that have both that symptom AND involve that organ.

Click on a resulting organization to see that organization’s complete answers to the survey on their Details Page. Definition prompts appear next to the terms using the same question mark icon from the filtering step. Contact information for each organization is included where available, so you can reach out to organizations you may be interested in learning from or partnering with.

You can print your results using the print button or share your results using the share button. The share button will give you a link to copy and paste for sharing purposes. Please do not share outside of your organization.

For visual accessibility, this tool has a button to enlarge the font size in the upper right corner. It is also compatible with “dark mode” settings on your Windows or Mac systems.
