The clinical hematologic change in 2 groups of progeny from mice carrying radiation-induced strain SEC ..cap alpha..-chain deficiencies was found to be similar to the hematologic alterations in persons with ..cap alpha..-thalassemia. The heterozygous deletion or inactivation of the ..cap alpha..-chain gene in mice caused an anemia similar to ..cap alpha..-thalassemina minor in persons. The ..cap alpha..-chain deficiency in mice created an erythrocytosis, reticulocytosis, and microcytic, hypochromic anemia comparable with the changes in human ..cap alpha..-thalassemia minor resulting from deletion of the ..cap alpha..-chain gene. These mouse mutants are the only known animal models of human thalassemia. A comparison of hematologic values obtained from progeny possessing an ..cap alpha..-chain gene deficiency and from progeny possessing a ..beta..-chain duplication suggested that the deficiency of ..cap alpha..-chain synthesis, rather than a simple imbalance between the amounts of ..cap alpha..- and ..beta..-chains produced, was primarily responsible for the altered hematologic characteristics in these ..cap alpha..-thalassemic mice.
