The table is based on the 200 best marker genes from the marker analysis of VH3-21+ versus non-VH3-21 B-CLL. O indicates observed gene number in the GO category; E, expected gene number in the GO category; R, ratio of enrichment for the GO category; and P, significance of enrichment for the GO category. Representative parent and child GO categories are shown. A detailed description of all GO categories is included as direct acyclic graphs (DAGs) in Supplemental Figure S2.

*

Nonsignificant GO category, but the “child” category showed significant enrichment.
