However, a comprehensive analysis of gene expression results clearly indicates significant differential expression of HERV-K_1q23.3, SLAMF1, IGHG2, HERV-K_22q11.23, IGLL1, HERV-K_9q34.11, and LRRC8A in breast cancer cells, with a significant correlation between HERV-K and its corresponding neighboring genes. The gene discussed is IGHG2; the disease is breast cancer.
