Study of gene expressions' correlation structures in subgroups of Chronic Lymphocytic Leukemia Patients.

•We utilized comparison of correlations of genes between M-CLL and U-CLL patients.•We applied SEM and graph modeling to study the differentiating structures.•Stronger correlations are found in U-CLL patients.•Community plots reveal more dense and interconnected communities in U-CLL cases.•HMGB1 and CD180 are in most differences of correlations between U-CLL and M-CLL.
