For example, PMID:18457324 entitled “Genetic polymorphisms in the carbonyl reductase 3 (CBR3) and the NAD(P)H:quinone oxidoreductase 1 (NQO1) genes in patients who developed anthracycline-related congestive heart failure after childhood cancer,” the paper primarily discusses the gene expression of congestive heart failure (CHF) patients who had childhood cancer. Here, CBR3 is linked to childhood malignant neoplasm.
