VEXAS Biobank


About this study

The objective of this study is to develop a biorepository of venous peripheral blood samples to carry out future multi-omic research on patients with VEXAS syndrome.

An adult auto-inflammatory syndrome caused by somatic mutations in the bone marrow myeloid precursors in the bone marrow has been recently identified and described by the National Institutes of Health (NIH). This condition has been termed VEXAS syndrome – which stands for Vacuoles, E1 enzyme, X-linked, Auto-inflammatory, Somatic
