Because an increased frequency of loss-of-function mutations in BAP1 in UM that become metastatic and an association between BAP1 mutation and worse prognosis/survival in UM patients were observed, we sought to examine the correlation of TFPI2 and BAP1 in mRNA expression levels from TCGA-UM and TCGA-CM data. Here, BAP1 is linked to cutaneous mastocytosis.
