Another integrative analysis of RNA-seq data of ~1000 breast tumors in TCGA identified GATA3-AS1 (ENSG00000197308), RP11-279F6 (ENSG00000245750), and AC017048 as highly expressed in ERα-positive versus ERα-negative breast tumors and normal breast tissue samples [295]. The gene discussed is ESR1; the disease is breast neoplasm.
