Abstract Introduction/Objective Vacuoles, E1 enzyme, X-linked, autoinflammatory, and somatic mutation (VEXAS) syndrome was first described in 2020. VEXAS is driven by a mutation in the UBA1 gene on hematopoietic progenitor cells that encodes the E1 ubiquitin-activating protein. Loss of this protein leads to various inflammatory clinical presentations ranging from dermatological, pulmonary, rheumatologic and hematologic. Many UBA1 variants have been identified. We did a systematic review focusing on a particular UBA1 variant gene mutation underlying this disease process. Methods/Case Report Databases were searched for articles discussing VEXAS syndrome until April 2024. Only case reports and case series in the English language were included. Data on patient demographics, clinical presentation, laboratory values, bone marrow findings, dermatologic presentation and skin biopsy findings were extracted. Results (if a Case Study enter NA) 332 articles discussing VEXAS syndrome were retrieved, of which 115 were case reports or case series. These were screened for patients carrying a p.Met41Leu UBA1 gene mutation and only the 25 patients with this genetic variant were ultimately included in our study. The average age was 68 years (59-81 years). 24/25 (96%) patients reported dermatologic symptoms ranging from erythema to urticarial eruptions to erythema multiforme. Fever was the second most common presenting complaint (76%) followed by arthritis (68%), chondritis (36%) and thromboembolic disease (28%). Macrocytic anemia was a common laboratory finding (65%). MDS was seen in 52% of the patients. All patients had hematopoietic progenitor cells with vacuoles. Sweet’s syndrome was the most common initial diagnosis (52%) as skin biopsies in most patients showed dermal edema and neutrophilic dermatoses/infiltration. Conclusion The c.121A>C, p.(Met41Leu) UBA1 variant is frequently related to cutaneous manifestations. In patients with clinical features of an inflammatory disorder with dermatological and hematologic abnormalities, testing for the p.Met41Leu UBA1 mutation might lead to an earlier diagnosis and prompt initiation of effective treatment.
