Our present data for renal cancers, together with our previous studies of colon (2) and brain tumors (1), establish that D17S5 hy permethylation is tightly coupled to 17p deletions and p53 gene mu tations in human cancers. Our results in renal cancer strongly suggest that this hypermethylation prece ...
