Summary of key gene expression differences. Gene expression levels for all study samples are shown depicting key differences for WM vs normal B-cell samples as well as WM patient intrapatient differences based on MYD88 and CXCR4 genotype. The heat map represents log₂ transformed TpM values with median and range TpM values listed for each relevant comparator. P values have been adjusted for multiple hypotheses testing using the Benjamini-Hochberg FDR.
