✦ Synopsis

Multiple hemi-and homozygous interstitial deletions at chromosome 3p have been found in different types of cancer, including non-papillary renal cell carcinoma (RCC). To determine the frequency and size of deletions, we have analyzed paired normal and tumor DNA obtained from short-term cultures of 104 non-papillary RCCs with 29 microsatellite markers covering the entire chromosome 3p region. Deletion mapping provided evidence for terminal deletion, with the most distal breakpoint between loci D3S1606 and D3S3666 in 94 cases, whereas constitutional heterozygosity was retained at all loci in 4 RCCs. In 6 cases, interstitial deletions were detected. Deletion mapping detected the smallest overlapping region between loci D3S3666 and D3S1560, which corresponds to an approx. 55 cM genetic distance.

Loss of heterozygosity (LOH) at chromosome 8p is associated with the progression of conventional (non-papillary) renal cell carcinomas (RCC). To determine the tumor suppressor gene locus, we carried out a deletion mapping of chromosome 8p at 10 microsatellite loci in 96 RCCs. LOH occurred in 32% of

The 9p21-23 chromosome region harbors a number of known and putative tumor-suppressor genes (TSGs). The best characterized gene in this area is p16 INK4A (CDKN2A). Alterations of its product have been observed in various malignancies, including non-small-cell lung carcinomas (NSCLCs). We earlier inv
