MBD4 and renal cell carcinoma: Following a comprehensive germline analysis of 19 genes linked to UM tumorigenesis, BAP1, or RCC in this large consecutive series of Finnish patients with UM, and considering our prior research on BAP1 and MBD4 in similar cohorts (Repo et al. 2020, 2019), the present findings affirm BAP1 as the primary germline contributor to predisposition to UM in Finland.
