The human platelet-derived growth factor alpha chain (PDGFA) gene maps to chromosome 7p22

The human PDGFA gene has been mapped previously to two different sites on chromosome 7 (7p21----p22 and 7q11.2----q21.1). Using in situ hybridization and human x mouse somatic cell hybrid lines we present data which confirm the localization of PDGFA to the terminal short arm of chromosome 7, at 7p22.
