CHD7 and small cell lung carcinoma: In addition, the GSVA of KEGG terms showed that CRG cluster A was abundant in metabolism-related pathways (citrate cycle TCA cycle, glycosylphosphatidylinositol GPI anchor biosynthesis), cancer-related pathways (small cell lung cancer, endometrial cancer), cell cycle–related pathways (cell cycle), and genomic stability–related pathways (mismatch repair, nucleotide excision repair) (Figure 4B).
