Abstract
Previous analysis of tumorβspecific constitutional LOH had identified a putative tumorβsuppressor gene (LOH18CR) active in osteosarcoma tumorigenesis, which mapped to a subregion of chromosome 18q linked to both familial Paget's disease and FEO. Using 9 new polymorphic loci within the previous minimal region of LOH, we have reduced the minimal region of LOH in osteosarcoma tumors to localize the LOH18CR locus to the distal end of chromosome 18q21.33. This new region is approximately 500 kb and contains at least 7 known genes; however, it excludes 2 previous candidate genes: TNFRSF11A (RANK) and BCL2. Β© 2003 WileyβLiss, Inc.

11q23-24 chromosome is a region containing frequent allelic loss (loss of heterozygosity; LOH) in human cancers. To examine cancer-related allelic loss in the region between D11S940 and APOC3, we used 17 polymorphic markers and allotyped 28 lung cancer-derived cell lines and their corresponding matc
Chromosome region 9p21 contains a tumor suppressor locus (p16) that may be involved in the genesis of several kinds of malignant tumors. To characterize the role of this gene in the development of soft-tissue tumors (STTs), we investigated the frequency of loss of heterozygosity (LOH) at this locus.
The tumor suppressor gene BRCA1 on chromosome 17q21 has been characterized and shown to be mutated in patients with familial breast and ovarian cancer. Several studies examined the relatives of women with breast cancer and noted an association with ovarian and prostate cancer. This study investigate
## Abstract We have analyzed the short arm of chromosome 1 using loss of heterozygosity (LOH) analysis in Wilms tumors (WT) to identify a minimal region of loss. 1909 WT, 22 malignant rhabdoid tumors of the kidney and 90 clear cell carcinomas of the kidney (CCSK) were subjected to LOH analysis usin
