Contrasting co-inheritance of alpha and beta mutations in delta beta thalassemia and hereditary persistence of fetal hemoglobin: a study from India.

CONCLUSION: We found 5/18(27.β) δβ-thalassemia cases with co-inherited alpha 3.7 deletion and 3/18 (16β) cases with IVS 1-5(G-C) mutation. Patients showed features of thalassemia intermedia phenotype among which those with co-inherited IVS 1-5(G-C) mutation showed severe phenotype as compared to those with co-inherited alpha 3.7 deletion. So, we highlight importance of genotyping of patients with δβ thalassemia or HPFH and coinheritance with inherited factors which plays crucial role in clinicopathological profile and setting up prenatal diagnostic protocol.
