Inversely, expression levels of the peroxisomal fatty acid transporters ABCD2 (logrank P = 2.2*10–5, HR 0.56, CI 0.43–0.74) and ABCD3 (logrank P = 1.4*10–7, HR 0.45, CI 0.33–0.61), as well as the mitochondrial transporters ABCB7 (logrank P = 6.4*10–10, HR 0.39, CI 0.29–0.54) and ABCB10 (logrank P = 1.1*10–6, HR 0.48, CI 0.36–0.65) were associated with significantly better outcomes in ccRCC and HNSCC. The gene discussed is ABCD2; the disease is nonpapillary renal cell carcinoma.
