According to varying .beta.-thalassemia genes synthesized in 51 homozygotes and 109 heterozygotes, 4 forms of .beta.-thalassemia were distinguished: .beta.-thalassemia major by the gene of classic .beta.-thalassemia (which in the minor state is characterized by an HbA2 increase); .beta.-thalassemia major by the gene of silent .beta.-thalassemia (which in the minor state does not induce an HbA2 increase); .beta.-thalassemia caused by combined genes of classic and silent .beta.-thalassemia; .beta.-thalassemia for which combined genes of .delta.beta.- and classic .beta.-thalassemia are responsible. The carriership of the silent .beta.-thalassemia gene in the Azerbaijan population described for the 1st time and its high frequency was discussed.
