Description

Scientific Background

Hereditary peripheral neuropathies are a group of the most common hereditary neurological diseases, which are clinically and genetically heterogeneous. Over 90 genes and alleles are involved, and age of onset is usually in the first or second decade of life, but manifestations later in life have also been observed. The classification is based on the clinical phenotype, mode of inheritance, age of manifestation, electrophysiological studies and the underlying pathogenic variant.

 

The main subtypes concern hereditary motor and sensory neuropathies (HMSN) or Charcot-Marie-Tooth disease (CMT, the most common form with an estimated prevalence of 1:1,200 to 1:2,500 in the general population), hereditary sensitive and autonomic neuropathy (HSAN or HSN), hereditary motor neuropathy (HMN or dHMN), and hereditary neuropathies with a liability to pressure palsies (HNPP). In addition, atypical phenotypes are reported whose symptoms overlap with spastic paraplegia, hereditary sensory neuropathy or amyotrophic lateral sclerosis.
