Hereditary sensory and autonomic neuropathy type V is a very rare autosomal recessive disorder, manifested by the loss of temperature and pain sensation. This condition can cause painless fractures, bone necrosis, osteochondritis, and neuropathic joint destruction, subsequent to repet-itive trauma. We report the case of a 7-year-old girl with ankle arthropathy that began 6 months after a minor trauma. The clinical condition was initially thought to be infectious or oncologic in nature. We later determined that the pathology was associated with the nerve growth factor gene mutation and proposed the pathogenicity of variant c.361C>T p.(Arg121Trp) based on clinical findings and genetic testing for the patient and her parents.
