What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Procedures mentioned: Urine samples, Blood draws, Questionnaires, Biopsies

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "Collect blood and urine samples from registrants to monitor levels of biomarkers, identify disease-modifying genes, and understand the mechanisms of the disease."
  • "We will collect blood samples up to three times a year and urine samples up to three times a year from Wolfram syndrome patients participating in the registry study."
  • "Administer an electronic activity assessment questionnaire one-time to all registrants."
  • "We will electronically administer a questionnaire to all individuals on the registry (self-report or parent proxy)."
  • "The revised questionnaire will be sent to all Registry participants to have a large sample size as well as more representation from individuals who are older or have more severe symptoms compared to those at the clinic."
  • "The questionnaire will serve as a needs assessment."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

In this study, the investigators hypothesize that studying monogenic variants with strong effect associated with severe insulin deficiency of Wolfram syndrome will provide important insights into the more complex type 1 and type 2 diabetes mellitus. Aim 1. Establish and maintain a registry of patients with Wolfram syndrome. An Internet based registry will be employed to enroll participants with the clinical diagnosis of Wolfram syndrome (insulin dependent DM and bilateral OA). Clinical information regarding age of diagnosis and progression of the disease will be collated and analyzed to better define its natural history, along with potential metabolic phenotypes such as glucose intolerance of heterozygous parents and unaffected sibs. If not already completed, blood for WFS1 sequence analysis will be obtained on the participants (parents and sibs also for control purposes) and sent to a CLIA certified lab to define the mutation. This information will benefit patient families and referring physicians by providing a genetic diagnosis and where indicated. The Wolfram Syndrome Registry will foster international collaborations to more efficiently and systematically collect Wolfram syndrome patients and their clinical and experimental data.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Official eligibility criteria

Any patient worldwide with a diagnosis of Wolfram syndrome and with access to the Internet can be enrolled in the Registry. Since the disease usually manifests in the first decade of life and tends to have an inevitably progressive course, participation of minors is important for establishing the natural course of the disease. Inclusion Criteria: Major Criteria * Diabetes mellitus \<16 yrs * Optic atrophy \<16 yrs Minor Criteria * Diabetes insipidus * Diabetes mellitus \>16yrs * Optic atrophy \>16 yrs * Sensorineural deafness * Neurological signs (ataxia, epilepsy, cognitive impairment) * Renal tract abnormalities (structural or functional) * 1 loss of function mutation in WFS1/CISD2 AND/OR family history of Wolfram syndrome Minimum Required * 2 major OR * 1 major plus 2 minor criteria OR * 2 pathological WFS1 or CISD2 mutations are identified Other variable suggestive evidence * Hypogonadism (males) * An absence of type 1 diabetes auto-antibodies * Bilateral cataracts * Psychiatric disorder * Gastrointestinal Exclusion Criteria: Inability of a patient and/or a guardian to obtain help with translation and thus, inability to understand questionnaire. Parent, Sibs, and Spouses: \- Parents, sibs, and spouses that are unaffected will be recruited as controls. Inclusion criterion is having the unaffected status and exclusion criterion is if the person cannot understand the Informed Consent Document.
