abstractText | At least six separate genes determining tissue- and organelle-specific isoforms of carbonic anhydrase are known. We have determined the chromosome location of one of these genes, carbonic anhydrase-3 (Car-3), in the mouse and carried out a linkage analysis of Car-1, Car-2, and Car-3. Car-3 has been assigned to band 3A2 by in situ hybridization. We identified a PstI restriction fragment length polymorphism between Mus spretus and Mus mus domesticus and, by using an interspecific backcross, showed that Car-3 is 2.4 +/- 1.7% SE from both Car-1 and Car-2, calculating genetic distance as percentage recombination. No recombinants were found between Car-1 and Car-2 in 100 backcross offspring, and when these data are combined with earlier results, these two loci are estimated to be 1.2 cM from each other at the 95% confidence interval. The three homologous carbonic anhydrase loci in man had earlier been assigned to 8q22, and the finding of linkage of Car-3 to Car-1 and Car-2 in the mouse adds another locus to the conserved segments on mouse chromosome 3 and human chromosome 8. |
