The majority of these markers clustered in three regions that have been suggested to be involved in the development of RCC, namely the p25 region, where the von Hippel Lindau (VHL) gene is located; the p21 region, which has been identified as a common region of overlap (SRO) of heterozygous deletions; and the p14 region, which is the location of the constitutional t(3;8) breakpoint occurring in an RCC family.
Numerous investigations suggest that one or more genes residing in the p14 to p21 region of human chromosome 3 are critical to the development of neoplastic diseases such as renal cell carcinoma and small-cell lung cancer (SCLC).
