Summaries for HSPB1 Gene

Entrez Gene Summary for HSPB1 Gene

  • The protein encoded by this gene is induced by environmental stress and developmental changes. The encoded protein is involved in stress resistance and actin organization and translocates from the cytoplasm to the nucleus upon stress induction. Defects in this gene are a cause of Charcot-Marie-Tooth disease type 2F (CMT2F) and distal hereditary motor neuropathy (dHMN). [provided by RefSeq, Oct 2008]

GeneCards Summary for HSPB1 Gene

HSPB1 (Heat Shock 27kDa Protein 1) is a Protein Coding gene. Diseases associated with HSPB1 include charcot-marie-tooth disease, axonal, type 2f and neuropathy, distal hereditary motor, type iib. Among its related pathways are MAPK signaling pathway and Akt Signaling. GO annotations related to this gene include identical protein binding and protein kinase C binding.

Disorders for HSPB1 Gene

(2) OMIM Diseases for HSPB1 Gene (602195)


  • Charcot-Marie-Tooth disease 2F (CMT2F) [MIM:606595]: A dominant axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. Nerve conduction velocities are normal or slightly reduced. Onset of Charcot-Marie-Tooth disease type 2F is between 15 and 25 years with muscle weakness and atrophy usually beginning in feet and legs (peroneal distribution). Upper limb involvement occurs later. {ECO:0000269 PubMed:15122254, ECO:0000269 PubMed:22206013}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Neuronopathy, distal hereditary motor, 2B (HMN2B) [MIM:608634]: A neuromuscular disorder. Distal hereditary motor neuronopathies constitute a heterogeneous group of neuromuscular disorders caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs. {ECO:0000269 PubMed:15122254}. Note=The disease is caused by mutations affecting the gene represented in this entry.
