Physical and transcriptional mapping of the 17p13.3 region that is frequently deleted in human cancer.
Studies of chromosomal losses at 17p13 have suggested the presence of at least two distinct regions for tumor suppressor genes, the TP53 region at 17p13.1 and a more distal region at 17p13.3. Within the latter region, Hypermethylated in Cancer 1 (HIC1) is located, a likely candidate for a tumor suppressor gene that has also been suggested to play a role in the pathogenesis of Miller-Diecker syndrome (MDS). However, single-gene isolation efforts have retrieved additional genes from 17p13.3 that could play a role in tumorigenesis. This indicates that the full potential of this chromosomal region with respect to disease-related genes has not yet been exhausted and that there may exist still unknown genes that contribute to tumorigenesis or to the complex MDS phenotype. To provide a basis for the systematic isolation and evaluation of such genes, we established a physical map over 1.5 Mb of 17p13.3 and assigned 29 transcriptional units within this region.
