To establish a biological link, we examined transcriptomes from normal human melanocytes (NHM; n = 308 samples from 35 patients) and tumors in the TCGA_SKCM (n = 363 samples) and the Lund melanoma cohorts (n = 214 samples) to determine if correlations between BAP1 expression levels and melanocyte lineage specifying genes exist (Supplemental Table 1 and Supplemental Figure 1A; supplemental material available online with this article; https://doi.org/10.1172/JCI195809DS1). Here, BAP1 is linked to melanoma.
