Somatic mutations in MYD88 and CXCR4 are determinants of clinical presentation and overall survival in Waldenström macroglobulinemia

Abstract
Key Points Activating MYD88 as well as nonsense and frameshift WHIM-like CXCR4 somatic mutations are common in WM. CXCR4 NS mutations are present in aggressive cases including hyperviscosity syndrome, and MYD88 status is a determinant of survival.
