Cluster analysis reveals distinct pediatric B-cell lymphoma types, highlighting immunodeficiencies and linking to Burkitt lymphomas.

This research aims to characterize pediatric mature B-cell non-Hodgkin lymphomas using RNA sequencing.
Analyzed B-cell lymphomas diagnosed in patients ≤24 years at St. Jude Children's Research Hospital
Conducted whole transcriptome analysis on 76 samples from 74 patients
Performed geneset enrichment analyses using lymphoma signatures from signatureDB database
Used UMAP for clustering based on variably expressed protein-coding genes
Identified three distinct clusters of lymphomas based on gene expression
Cluster 1 contained predominantly Burkitt lymphomas, while Cluster 3 included diverse high-grade lymphomas
Characterized cases with underlying immunodeficiencies, indicating their influence on disease presentation

Stephanie B. Dixon (2025) studied this question.
