Roadmap2Rare

Sponsored tools and tests to navigate rare disease diagnoses

Sanofi Canada is working in collaboration with Revvity Omics to offer the Roadmap2Rare Diagnostic Program – a complimentary genetic and biochemical testing program available to Canadian clinicians. This program is sponsored to address unmet testing needs in the rare disease space.


For more information about Sanofi Canada’s other sponsored Roadmap2Rare services, click here.

The Roadmap2Rare Diagnostic Program is not intended to and should not interfere in any way with a health care professional’s or patient’s independent judgement and freedom of choice in the testing and treatment options for these diseases. Health care professionals and patients should always consider the full range of testing and treatment options and select those most appropriate for the individual patient.

About lysosomal storage disorders

The lysosomes are required for the breakdown of intracellular molecules and compounds of all sizes. The lysosomal interior is an acidic environment and contains several different enzymes. Defects in these lysosomal enzymes result in an accumulation of the substrate in the lysosome eventually disrupting tissue function leading to enlarged and impaired organs. The affected cell systems will vary with the disorder, but all disorders involve multiple organ systems.

Suspicion of a lysosomal storage disorder can come from the physical exam (e.g. organomegaly, skeletal abnormalities, corneal clouding, or coarse features) and developmental assessment. Developmental delay with regression and/or organ dysfunction that is progressive is a hallmark of a storage disorder. Progressive cardiac, renal, hematological, or nervous system dysfunction occurring in a younger population than is typical would also prompt consideration of these disorders (e.g. renal disease, arrhythmias, valve disease, stroke, and peripheral neuropathy).

There is usually a continuum of severity and LSDs without obvious dysmorphic features or developmental delay are underrecognized. Due to the overall rarity of these conditions and their clinical heterogeneity, lengthy diagnostic delays and missed diagnoses are common. 

Mobile phlebotomy

Dried Blood Spot (DBS) sample collection is offered via mobile phlebotomy when on-site/in-clinic collection is difficult for a patient. Mobile phlebotomy is available for enzyme activity/biomarker tests and single gene sequencing (it is not available for multi-gene panel sequencing or familial variant tests; for these, patient self-collection can be arranged by Revvity Omics). Mobile phlebotomy is provided by ExamOne, a third-party service provider, and available for patients who:

  • Have a medical condition, recent hospitalization, or recent surgery which restricts travel, or are otherwise immobile and unable to attend appointments outside the home.
  • Lack access to transportation
  • Do not live close to any draw sites

For more information, see below for a list of frequently asked questions. Please call Revvity Omics client services at 1-866-354-2910 for any additional questions or concerns.

  • To take advantage of this service for your patient, requestors should complete the Mobile Phlebotomy Sample Collection Request section on the requisition form along with all other sections of the requisition form and send to Revvity Omics Client Services at Genomics@revvity.com.
  • Once your order is received, ExamOne will contact the patient to coordinate the appointment and ship necessary materials for sample collection.

How to order

1. Test Selection and place order

Select the correct test for your patient, and fill out the appropriate Roadmap2Rare Requisition Form

  • Please make sure that all sections are completed, and that the patient has signed the informed consent form
2. Specimen collection and shipment

Collection by the health care provider

Obtain a sample for testing from the patient using one of the provided Revvity Omics test packs. If you do not have a kit available in your office, please contact us here and we can have one sent out to your office.

  • Ensure that the patient sample is labeled with the patient’s name and date of birth.
  • Please note that all biochemical assays require a Dried Blood Spot (DBS) sample. Step-by-step instructions for collecting a sample can be found here.
  • Samples may be submitted without a collection kit by following the guidelines for specimen requirements and completing the requisition form.

Package the patient sample, informed consent form, and test requisition form back into the test kit, and utilize the included pre-paid shipping label to return the kit to Revvity Omics for processing.

  • As a patient’s clinical presentation is an essential part of fully interpreting genetic test results, we ask that you kindly include any applicable medical records or clinical notes with the sample at the time of test submission.
  • Collection coordinated by Revvity Omics
  • On the requisition form you can request Revvity Omics coordinate mobile phlebotomy (available for enzyme activity/biomarker testing and single gene sequencing). Mobile phlebotomy can also be requested through the Client Portal, or through the kit order URL.
  • Revvity Omics can arrange patient self-collection for tests performable from Saliva Swabs (multi-gene panel testing and familial variant testing). Patient self-collection can be requested through the Client Portal, or through the kit order URL.
  • For mobile phlebotomy, a DBS kit is mailed to the patient ahead of their in-home collection appointment. For patient self-collection, a Saliva Swab kit is mailed to the patient with instructions for collecting the sample and mailing it back to Revvity Omics.
3. Get results

Once Revvity Omics receives the sample, you will receive phone call to report abnormal findings, with a written report to follow within the established turnaround time for the ordered test. Bundled tests will be reported together in one comprehensive result.

    FAQs
  • What sample collection types are available through mobile phlebotomy?

    Dried Blood Spot (DBS) sample collection is available through mobile phlebotomy. At the time of service request by the provider, a DBS sample pack will be sent to the patient ahead of the mobile phlebotomy appointment.

  • Are there any limitations for pediatric patients?

    DBS sample collection is available to patients 13 years and older.

  • Is there any additional cost for mobile phlebotomy to the patient?

    No, mobile sample collection is included with the sponsored testing at no cost to the patient.

  • What are the days/hours of availability for appointments, and are there any regions in Canada that are excluded?

    Appointments can be scheduled Monday-Friday 7AM-1PM EST.

    Phlebotomists are available throughout Canada, but some rural areas may need additional time for scheduling.

  • What if ExamOne is unable to get in touch with the patient to schedule the appointment?

    ExamOne will make 3 attempts to reach the patient. If they are unable to get in touch with the patient to schedule an appointment, ExamOne will contact the provider requesting the service to discuss further steps.

  • What does the patient need to provide at the time of appointment?

    The patient will be asked to provide identification to the examiner and will need to have on-hand the DBS collection pack that was mailed to them in advance.

  • Can the appointment be rescheduled if complications arise before or during?

    Yes, once an appointment is scheduled, ExamOne will provide a scheduling coordinator’s number to use for any scheduling needs before the appointment. If any issues arise during the appointment that ExamOne is unable to immediately resolve, ExamOne will notify Revvity Omics of the unsuccessful collection and determine how to move forward. The appointment can be re-scheduled if necessary.
