More than 30 heritable HSP27 mutations are implicated in Charcot‐Marie‐Tooth (CMT) disease (Nefedova et al,2015; Adriaenssens et al,2017; Echaniz‐Laguna et al,2017; Muranova et al,2020; Vendredy et al,2020), a group of neuropathies that affects ca. 1 in 2,500 individuals and is the most common inherited disorder involving the peripheral nervous system (Barisic et al,2008; Timmerman et al,2014). This evidence concerns the gene HSPB1 and neuropathy.
