In a The Cancer Genome Atlas (TCGA) comparative study between normal breast tissue (n = 113) and breast tumors (n = 1109), COL11A1, COL12A1, COL1A1, COL1A2, COL5A1, and COL5A2 transcripts were upregulated in breast cancer and could discriminate between the two breast tissues. Here, COL11A1 is linked to breast neoplasm.
