CMT4 is a rare subtype of CMT, a genetic, neurological disorder that causes damage to the peripheral nerves — tracts of nerve cell fibers that connect the brain and spinal cord to muscles and sensory organs.

CMT4 is a subtype of CMT that is inherited in an autosomal recessive pattern.

“As genetic therapies quickly become a real option for CMT patients,

this new HNF project is very exciting for patients, physicians, and researchers alike”

– Dr. Stephen Züchner, MD, PhD Professor for Human Genetics and Neurology Chair, Dr. John T. Macdonald Foundation Department of Human Genetics Co-Director, John P. Hussman Institute for Human Genomics University of Miami Miller School of Medicine and founder of The Genesis Project

If you have been diagnosed with CMT4 or have had genetic testing, but not received a confirmed genetic diagnosis, join the Global Registry for Inherited Neuropathies (GRIN). We are here to help you navigate the complexities when your genetic report comes back inconclusive. For more information, contact Joy Aldrich, GRIN Registry Coordinator at [email protected]
