PDE1C and basal cell carcinoma: In this study, we collected 12 targets of CALML5, including TGM3, PDE1C, and CASP14. Smirnov et al. [30] showed that TGM3 is absent in melanocytes as well as SKCM samples and that the expression pattern of TGM3 renders it a potential specific marker for basal cell carcinoma diagnosis.
