We did not identify any vacuole-related differences in circulating immature myeloid cells between VEXAS patients and UBA1-WT 'VEXAS-like' patients. The similar vacuolization of circulating immature myeloid cells between VEXAS and UBA1-WT patients is explained by the main bloodstream passage of late precursors, in which the vacuolization is already similar in bone marrow in both cases.
