OCA2 and skin basal cell carcinoma: Moreover, given that our pathway analyses highlighted the involvement of the melanin metabolic and biosynthetic process in BCC pathogenesis, drugs targeting genes (i.e., TRPC1, SLC45A2, TYRP1, TYR, PMEL, DCT, OCA2, MYO5A, MC1R, CTNS, ASIP, DDT, and BCL2) involved in those pathways could be potential therapies for BCC.
