The mean expression (in reads per million, or RPM) of CYP4Z1 in adjacent normal tissue (all matched normal tissue samples at TCGA combined), BRCA tissue (all racial groups combined), and separately for CA, AS, and AA breast tumor tissue was 36.9, 92.2, 101, 52.7, and 63.6, respectively. Here, CYP4Z1 is linked to breast neoplasm.
