HMGA1P6 and HMGA1P7, two pseudogenes of HMGA1 competing for endogenous RNA, can also lead to cancer when they are dysregulated, and the expression of HMGA1P7 is related to the levels of H19 and IGF2 in breast cancer, which is linked to the high double strand breaks in breast cancer cells 57. The gene discussed is HMGA1P6; the disease is breast cancer.
