Summary The following loci, on human chromosome 13, have been newly assigned to sheep chromosome 10 using chromosomally characterized sheep‐hamster cell hybrids: gap junction protein, beta 2, 26 kDa (connexin 26) (GJB2); gap junction protein, alpha 3, 46 kDa (connexin 46) (GJA3), and esterase D/formylglutathione hydrolase (ESD). This assignment of ESD is consistent with comparative mapping evidence, but not with an earlier report of it on sheep chromosome 3p26‐p24. Cell hybrid analysis confirmed the location of another human chromosome 13 locus, retinoblastoma 1 (including osteosar‐coma) (RBI), and the anonymous ovine genomic sequence RP11 on sheep chromosome 10. Isotopic in situ hybridization was used to regionally localize RP11 on to sheep 10q15‐q22. The location of microsatellites AGLA226, OarDB3, OarHH41, OarVH58, and TGLA441, previously assigned to sheep chromosome 10 by linkage analysis, was confirmed by polymerase chain reaction using the cell hybrid panel. These mapping data provide further evidence that sheep chromosome 10 is the equivalent of cattle chromosome 12, and that these chromosomes show extensive conserved synteny with human chromosome 13.
