Side-by-side comparisons between MSI1 and MSI2 in a set of 1,310 DLBCL patient tissues (GSE181063 dataset) showed that both known MSI2 transcript variants were strongly overexpressed compared to MSI1 (p < 0.001) while differences between transcript variants were less pronounced (Figure 2C). Here, MSI1 is linked to diffuse large B-cell lymphoma.
