To highlight that the abovementioned associations with the immune-cell infiltrations are specific to the SP sub-family of Bromodomain proteins, we selected the ATAD2 gene as a representative of other BrD proteins and demonstrated that the association between ATAD2 gene expression and immune cell infiltration in solid tumors was not so consistent and significantly varied between tumor types and immune-cell types. The gene discussed is ATAD2; the disease is neoplasm.
