Abstract

In spite of high incidence of α-thalassemia as the most common inherited disorder of hemoglobin (Hb) production in Southeast Asia, the role of point mutations in this aspect not still well known. This fact can lead to missing rare variants of α-thalassemia mutations by the routine screening, which they may need to be screened for possibility of causing Hb H disease. In this study we found two insertions in alpha1 gene which cause to Hb H disease. One of the insertions, 108/109, is a new findings and another one, codon 44, is the mutation which has been followed for the first time. These new molecular findings about changes in α-globin production which results in decreased of hemoglobin (Hb) value, have high-impact clinical importance.
