Genetic factors for nerve susceptibility to injuries – Lessons from PMP22 deficiency

Research output: Contribution to journalArticlepeer-review

Abstract

Genetic factors may be learnt from families with gene mutations that render nerve-injury susceptibility even to ordinary physical activities. A typical example is hereditary neuropathy with liability to pressure palsies (HNPP). HNPP is caused by a heterozygous deletion of PMP22 gene. PMP22 deficiency disrupts myelin junctions (such as tight junction and adherens junctions), leading to abnormally increased myelin permeability that explains the nerve susceptibility to injury. This finding should motivate investigators to identify additional genetic factors contributing to nerve vulnerability of injury.
