Distal hereditary motor neuropathy (dHMN), also known as distal spinal muscular atrophy (dSMA), comprises a group of inherited peripheral neuropathies with great clinical and genetic heterogeneity, mainly characterized by progressive atrophy and weakness of distal muscle without clinical or electrophysiological sensory abnormalities. Next-generation sequencing is widely applied as an effective diagnostic technique to discover pathogenic genes in patients with dHMN. To date, at least 23 causal genes have been identified to be associated with dHMN, several of which encode chaperones. Here, we report a dHMN patient due to a homozygous c.184C>T variant in the DNAJB2 gene with rare neuropathic and myopathic characteristics on pathological examination. These findings might broaden the mutational spectrum of DNAJB2 and expand the tissue involvement of DNAJB2-related presentations.
