pressure palsy

The main effect of HNPP are pressure palsies.

Carpal tunnel is also a feature of a form of Charcot-Marie-Tooth syndrome type 1 called hereditary neuropathy with liability to pressure palsies.

Hereditary Neuropathy with Liability to Pressure Palsy (HNPP) is a peripheral neuropathy (disorder of the nerves).

Various mutations of the gene are causes of Charcot-Marie-Tooth disease type IA, Dejerine-Sottas disease, and hereditary neuropathy with liability to pressure palsy.

If, instead, the chromosome with the deletion were passed on to the next generation, the result would be another nerve disorder, a milder one called H.N.P.P., which stands for hereditary neuropathy with liability to pressure palsies.
