We have mapped five genes encoding protein tyrosine kinases (PTKs) to the pericentromeric region of human chromosome 4.PTK4andTYRO4, which encode nonreceptor intracellular PTKs, are located at 4p12 and 4q13, respectively. The other three genes,PDGFRA, KIT, andKDR, encode type III transmembrane receptor PTKs for known ligands. We have developed a contig of 29 yeast artificial chromosomes (YACs) spanning approximately 2 Mb of DNA at 4q12 that includesPDGFRA, KIT, andKDR, and we have used this YAC contig to map 12 different sequence-tagged sites in this region.PDGFRA, KIT, andKDRthus constitute a cluster of genes at 4q12 encoding closely related type III receptor PTKs. Mutations of the humanKITgene result in piebaldism, an autosomal dominant disorder of melanocyte development.
