Cluster enrichment scores for selected significantly enriched functional clusters containing terms showing a significant change (P < 0.05) after Benjamini–Hochberg correction for multiple testing, and the term(s) most representative of each cluster. The genes associated with the most represented terms are shown in Supplementary Table S2.
