abstractText | Three induced, heritable mutations in the mouse cause alpha-thalassemias. The adult alpha-globin genes on each mutant chromosome are no longer expressed. Embryos heterozygous for one normal and any of the three mutant chromosomes also seem to be deficient in embryonic alpha-globin-like x-globin, suggesting that the x-globin gene is nearby and also inactivated. A normal genetic polymorphism for a specific EcoRI site in or around the mouse alpha-globin gene complex has been used here to show that each of the three mutated chromosomes has a deletion that includes the segment of a 12-kilobase EcoRI band which normally carries one of the two adult alpha-globin genes. The deletion of the comparable part of the second alpha-globin gene site is also inferred. Nonetheless, a 4.7-kilobase EcoRI segment which carries a characterized alpha-globin-like pseudogene is still present in each mutant. These mutations were recovered after triethylenemelamine or x-ray treatments. |
