The Natural History of TRPV4 Neuropathy
Sponsor
Johns Hopkins University
Enrollment
70 participants
Start Date
Dec 15, 2023
Study Type
OBSERVATIONAL
Conditions
Summary
The goal of this research is to document the natural history of neuropathy in patients with a confirmed genetic mutation in the TRPV4 gene. The investigators are searching for patients willing to participate in a 6-year long study to document the symptoms of TRPV4-associated disease and their progression over time. Participation requires annual study visits at Johns Hopkins for adult and juvenile participants.
Eligibility
Min Age: 3 YearsMax Age: 80 Years
Inclusion Criteria4
- Patient is aged 3-80 years with a documented mutation in the TRPV4 gene and a clinical phenotype consistent with TRPV4-associated disease (as determined by the investigator) OR
- The patient has a first-degree relative (parent, child, sibling, half-sibling, aunt, uncle, grandparent, or grandchild) with a documented disease-causing mutation AND a clear link between that family member and the affected patient AND a clinical phenotype consistent with TRPV4-associated disease.
- Patients with a variant of unknown significance in TRPV4 and a clinical phenotype possibly consistent with TRPV4-associated disease will be eligible for initial enrolment, but continued eligibility will be determined based on whether the observed clinical phenotype is consistent with TRPV4-associated disease (as determined by the investigator).
- Participant or legal guardian for patients under 18 years of age is capable of giving signed informed consent.
Exclusion Criteria2
- Medical history of other concomitant neurological disease or clinically significant physical exam/laboratory result that, in the opinion of the investigator, would render the patient being unsuitable for the study.
- Patients with a TRPV4 variant of unknown significance who are initially enrolled but then deemed to be unlikely to have a phenotype consistent with TRPV4-associated disease will no longer be eligible and their clinical data will be deleted.
