Wolfram Syndrome and WFS1-related Disorders International Registry and Clinical Study
Recruiting now
Conditions studied: Wolfram Syndrome, Diabetes Mellitus, Optic Nerve Atrophy, Deafness, Diabetes Insipidus, Ataxia
In brief
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.

You may not qualify if…
- 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.
