This has led to the prediction for clustered EGF-TM7 genes located on the short arm of human Chr 19. To extend our characterization of the mouse F4/80 gene, The Cystatin S gene maps to rat we undertook gene mapping studies described in this report. In Chromosome 3, to which D1mgh18 is accordance with the human nomenclature, the gene encoding the re-assigned from Chromosome 1 F4/80 molecule will hereafter be referred to as Emrl. The position of the EMR1 gene on the short arm of human Chr 19 (19p13.3) extends the homology relationship between this region of the hu- M.
