High expression of IGHG2 is also a positive survival parameter in different solid tumors when validated using TCGA (The Cancer Genome Atlas) data, including head and neck squamous cell carcinomas (TCGA-HNSCC) and breast invasive carcinoma (TCGA-BRCA) (Supplementary Figure S7). The gene discussed is IGHG2; the disease is head and neck squamous cell carcinoma.
