HbE and 74 (9.3%) of the remaining people carried genes with a combination of α and β thalassemia mutations. The mean MCV values of the groups carrying phenotypes α+, α0, βE and β0 were 81.2fl, respectively; 67.8fl; 77.4fl and 64.7f; The mean value of MCH of groups carrying phenotypes α+, α0, βE and β0 is 26.5pg, respectively; 21.5pg; 25.4pg and 20.2pg; Carriers of the α thalassemia gene have a normal or slightly decreased HbA2 ratio.
