Associated Genetic Biomarkers

Overview

NCI Definition: A B-cell non-Hodgkin lymphoma composed of small lymphocytes which surround and replace the splenic white pulp germinal centers. It involves the spleen and splenic hilar lymph nodes, bone marrow, and often the peripheral blood. When lymphoma cells are present in the peripheral blood, they are usually, but not always, characterized by the presence of short polar villi. (WHO) [1]

Splenic marginal zone lymphomas most frequently harbor alterations in XPO1, SOS1, SMO, SLC25A13, and RARA [2].

Most Commonly Altered Genes in Splenic Marginal Zone Lymphoma

XPO1 Mutation, XPO1 E571K, SOS1 Mutation, SOS1 I461V, and SMO Q745R are the most common alterations in splenic marginal zone lymphoma [2].
