The beta-thalassemia (thal) minor phenotypes with normal Hb A2 levels and decreased MCV and MCH values are relatively rare beta-thal traits. Here, we describe a family with normal Hb A2 and decreased MCV and MCH levels. Amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) revealed the IVS-II-1 (G-->A) mutation in the beta-globin gene of the proband and her father. Direct sequencing of the gamma-globin gene of the proband and her father also revealed a previously reported variant called Hb A2-Troodos [gamma116(G18)Arg-->Cys] [in cis with the IVS-II-1 (G-->A) beta0-thal mutation]. This is the first case report of Hb A2-Troodos in association with the beta0 IVS-II-1 mutation. Reduced Hb A2 expression by a concomitant Hb A2 beta-thal in cis or trans, may cause problems in carrier diagnostics, and eventually in genetic counseling and prenatal diagnosis when insufficient molecular analyses are performed.
