Who can join
The official eligibility criteria
Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.
Inclusion Criteria:
All patients must agree to take part in the study and sign a consent form. A teenager (age 13-17 years) considering enrolling must agree to take part in the study and sign an assent form (depending on local ethics committee requirements).
Additional inclusion criteria are described below.
Inclusion Criteria: CMT1A Gene Modifier Study
Patients must have at least one of the following:
1. Patient has a documented PMP22 duplication. AND/OR
2. Patient has a first or second degree relative (parent, child, sibling, half- sibling, aunt, uncle, grandparent, grandchild, niece, or nephew) with a documented PMP22 duplication AND a clear link between that family member and the affected patient AND a phenotype consistent with CMT1A.
i. A clear link is necessary for a second-degree relative. For example, if a grandparent is affected and has a PMP22 duplication, and the parent does not have any signs, symptoms, or electrophysiology consistent with CMT1A, there is no clear link.
ii. In cases where clear links are not available, genetic testing is required for the patient or the first degree family member who is not clearly affected.
Inclusion Criteria - Patients for CMT Exome Project
a. Patient has demonstrated neuropathy on nerve conduction studies or clinically diagnosed genetic neuropathy, in the opinion of the investigator or genetic counsellor.
Inclusion Criteria - Controls for CMT Exome Project
1. Person is a family member of a CMT patient who is enrolled in the CMT Exome Project.
AND one of the following:
2. Person does not have a peripheral neuropathy, in the opinion of the investigator or genetic counsellor.
OR
3. Person is suspected to have a peripheral neuropathy, but has not been examined at an INC site.
Exclusion Criteria
1. Patient does not wish to participate or does not sign a consent form.
2. For CMT Exome Project, patient has a genetically confirmed form of CMT (i.e. mutation in MFN2 causing CMT2A, mutation in GARS causing CMT2D, etc.).
3. Patients with known neuropathy from a non-genetic source, such as chemotherapies (i.e. Vincristine, Taxol, Cisplatin), diabetes, alcoholism will be evaluated independently so that genetic contributions to their effects on CMT1A phenotypes can also be analyzed.

Not medical advice.
Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
