title: The human PECAM1 gene maps to 17q23.
abstract: We have determined the chromosomal and regional location of the gene encoding PECAM-1 (termed PECAM1 by GBD nomenclature) using a polymerase chain reaction (PCR)-based analysis of somatic cell hybrids. Analysis of a somatic cell hybrid chromosome panel established that the PECAM1 gene is on chromosome 17. Interestingly, several adhesion molecules expressed on platelets and endothelium also localize to chromosome 17: the GP1BA locus (glycoprotein (GP) Ibalpha) has been provisionally mapped to the region 17p12-pter, the ITGA2B (GPIIb) and the ITGB3 (GPIIIa) loci have been confirmed to the region 17q21.32; and the ICAM2 locus has been provisionally mapped to the region 17q23-q25. To determine if the PECAM1 locus colocalizes with any of the loci for these adhesion molecules, PCR-based analysis of a regional mapping panel for human chromosome 17 was conducted. We found that the PECAM1 locus is on the long arm of chromosome 17, in the region q23-qter. To confirm this observation and obtain a more precise localization of the PECAM1 locus, fluorescence in situ hybridization was conducted. Together our data allowed assignment of the PECAM1 locus to the region 17q23.
