Complex regional pain syndrome (CRPS) is a chronic pain condition affecting the limbs. Two subtypes are recognized in this dataset: complex regional pain syndrome type 1 (MONDO:0011441) and complex regional pain syndrome type 2 (MONDO:0020572). Prevalence is recorded as unknown in this packet. Affected organ systems identified in this packet include growth-related structures and the integument (skin). CRPS affects the extremities and is documented across both pediatric and adult populations, though no epidemiological frequency data are available in the packet's prevalence field.
Clinical features recorded in this packet's phenotype data include limb pain, allodynia, dysesthesia, erythema, edema of the upper limbs, pedal edema, dry skin, involuntary movements, slow-growing nails, trophic changes related to pain, somatic sensory dysfunction, and abnormality of hair growth. Affected organ systems in this packet encompass growth-related structures and the integument (skin). These phenotype entries collectively document sensory, autonomic, and trophic features as recorded in the packet's dataset.
No causative genes or associated molecular data are recorded in this packet's known genes field. No inheritance pattern is specified, consistent with the condition's characterization in the packet as lacking a documented genetic etiology. No ClinGen gene validity or ClinVar variant data are present for complex regional pain syndrome in this dataset.
No structured diagnostic criteria are recorded in this packet's available fields. Diagnostic information for complex regional pain syndrome is not enumerated in the accessible dataset. No molecular diagnostic markers are listed. The recognized subtypes — type 1 and type 2 — provide a classification framework documented in the MONDO ontology within this dataset.
No approved treatments or foundational therapies are recorded in this packet's treatment fields. No FDA-approved agents are listed for complex regional pain syndrome in the available data. Ten clinical trials related to this condition are documented in ClinicalTrials.gov data within this packet, including studies of non-invasive brain stimulation for pain avoidance behavior in chronic pain (NCT07791966, recruiting), hyperbaric oxygen therapy in CRPS (NCT07446712, recruiting), and intravenous AMBTX-01 (neridronate) for CRPS type 1 (NCT07210515, recruiting). ClinicalTrials.gov is the authoritative registry for current enrollment and eligibility information.
