About this trial

This project includes two projects. One is looking for new genes that cause Charcot Marie Tooth disease (CMT). The other is looking for genes that do not cause CMT, but may modify the symptoms a person has.

Eligibility criteria

Qualifiers

Patient has a documented PMP22 duplication. AND/OR

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.

Person is a family member of a CMT patient who is enrolled in the CMT Exome Project.

Person does not have a peripheral neuropathy, in the opinion of the investigator or genetic counsellor.

Disqualifiers

Patient does not wish to participate or does not sign a consent form.

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.).

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.
