TFDP1 and bladder transitional cell carcinoma: RBL2 also exhibits significant correlation exclusively in tumor tissues of OV, BLCA, and CHOL, indicating a cancer type-specific correlation between RBL2 and PIP4K2A. Another example is TFDP1, this gene exhibits extraordinarily strong association with PIP4K2A. Same as RBL2, TFDP1 also shows evident association with PIP4K2A in four large samples of B-ALL subtypes as well as all types of leukemia.
