Figure 2 was modified from Figure 1 of Koster et al., originally published under an all-rights-reserved copyright. The authors have now obtained permission from the publisher (Wiley) for reuse of the modified figure. The corrected caption of Figure 2 appears below:

“UBA1 gene structure, spectrum of mutations identified in VEXAS and UBA1 isoforms. (A) UBA1 gene structure, spanning amino acids 1 to 1058, with various functional domains highlighted in distinct colours. These include the nuclear localization signal (first 11 codons, NLS), the inactive adenylation domain (IAD), the first segment of the active catalytic cysteine (FCCH), the active adenylation domain (AAD), the second segment of the active catalytic cysteine (SCCH), and the C-terminal Ubiquitin Fold Domain (UFD). The diagram also marks representative mutations. (B) Two primary UBA1 isoforms: UBA1a, which begins at methionine 1 (M1, depicted in black), and UBA1b, starting at methionine 41 (M41, shown in green). Additionally, the non-canonical isoform UBA1c is displayed, initiating at methionine 67 (M67, indicated in dark blue). Modified with permission from Koster et al., Am J Hematol.
