GeneDxGeneDx currently provides a variety of options for single gene and panel testing to diagnose hereditary neuropathies. Testing can be ordered through a health care provider, such as a physician or genetic counselor. The most comprehensive panel option, the Hereditary Neuropathy panel, includes sequencing and deletion/duplication analysis of well-vetted genes associated with Charcot-Marie-Tooth neuropathy, as well as hereditary motor neuropathies and hereditary sensory and autonomic neuropathies. It is well established in the scientific literature that variants in four genes, PMP22, MPZ, MFN2 and GJB1, account for over 90% of molecular diagnoses in patients with CMT. Therefore, GeneDx offers a Core CMT panel, which targets these four most common genes. In addition, GeneDx offers other multigene panels based on a patient’s clinical presentation, e.g. the Axonal CMT panel and the Demyelinating CMT panel. Several additional neuropathy-related single gene and panel tests are also available through GeneDx.

Panel and single-gene testing has a turn around time of four weeks and PMP22 deletion/duplication analysis is available in two weeks. For more information about neuropathy testing by GeneDx, please visit the GeneDx website, or call 301-519-2100 and ask to speak to a neurology genetic counselor.

For those patients who do not receive a molecular diagnosis through single gene or panel testing, GeneDx also offers whole exome sequencing or whole genome sequencing. For more information on these comprehensive testing options, please visit the GeneDx website or call 301-519-2100 and ask to speak to an exome genetic counselor.

Patient-Friendly Billing Policy

  • GeneDx accepts all commercial insurance policies.
