OMIM : 54 'Primary erythermalgia' is an autosomal dominant disorder characterized by childhood or adolescent onset of episodic... (133020) more...

MalaCards based summary : Erythermalgia, Primary, also known as small fiber neuropathy, is related to sodium channelopathy-related small fiber neuropathy and breast cancer, and has symptoms including constipation, myalgia and pain. An important gene associated with Erythermalgia, Primary is SCN9A (Sodium Voltage-Gated Channel Alpha Subunit 9), and among its related pathways/superpathways are Activation of cAMP-Dependent PKA and Developmental Biology. The drugs Carbamazepine and Analgesics have been mentioned in the context of this disorder. Affiliated tissues include skin and eye, and related phenotype is integument.

Genetics Home Reference : 25 Small fiber neuropathy is a condition characterized by severe pain attacks that typically begin in the feet or hands. As a person ages, the pain attacks can affect other regions. Some people initially experience a more generalized, whole-body pain. The attacks usually consist of pain described as stabbing or burning, or abnormal skin sensations such as tingling or itchiness. In some individuals, the pain is more severe during times of rest or at night. The signs and symptoms of small fiber neuropathy usually begin in adolescence to mid-adulthood.

UniProtKB/Swiss-Prot : 66 Primary erythermalgia: Autosomal dominant disease characterized by recurrent episodes of severe pain associated with redness and warmth in the feet or hands.
