Hereditary neuropathy with liability to pressure palsies (HNPP), which is a peripheral myelin protein 22 (PMP22) gene‐related genetic disorder similar to CMT type 1A, is characterized by repetitive painless mononeuropathies and plexopathies triggered by minor trauma of the peripheral nerves (Mouton et al., 1999). This evidence concerns the gene PMP22 and hereditary neuropathy with liability to pressure palsies.
