Interestingly, cancer-type SLCO1B3, encoding for a family of anion-transporting polypeptides, has been isolated selectively in RDEB-cSCC cells, and its levels on liquid biopsies of tumor-bearing mice were higher than those of healthy subjects, thus displaying an interesting potential role as a biomarker for cSCC in RDEB patients [31]. Here, SLCO1B3 is linked to recessive dystrophic epidermolysis bullosa.
