The six loci, β-globin (HBBC), parathyroid hormone (PTH), oncogene c-Ha-ras-1 (HRAS1), insulin (INS), calcitonin (CAL) and catalase (CAT) loci, have been mapped to 1 lp in the order: CAT-CAL-PTH-HBBC-(HRASl-INS). The purpose of the current study was to examine the linkage relationships, especially the multipoint relationships of these loci in detail. In the 18 families studied, a significant sex difference in recombination was found for the HBBC: HRAS1 linkage with more recombination in the male parent than the female parent (22 vs. 2%). The results of the multipoint analyses provided further evidence for the order CAT-CAL-PTH-HBBC-(HRASl-INS); however, the order of the last two tightly linked loci is still not clear.
