Hereditary neuropathy with pressure palsies (HNPP)
Hereditary Neuropathy with Pressure Palsies (HNPP) is a genetic disorder that affects the peripheral nerves, leading to recurrent episodes of numbness, tingling, and muscle weakness. These symptoms are typically triggered by minor trauma or pressure to nerves, such as prolonged sitting or repetitive movements. HNPP is caused by mutations in the PMP22 gene, which provides instructions for producing a protein essential for the function of myelin, the protective covering around nerves.
