چکیده مقاله:

Abstract β-thalassemia major (β –TM) is the most common thalassemia severe phenotype among Iranians. In recent years, molecular understanding of pathogenesis of β –TM has provided a great opportunity regarding diagnostic issues. Creating comprehensive molecular databases provides highly sensitive diagnostic tools for β –TM and effective prenatal diagnosis (PND) molecular screening tests. Despite a large body of research on molecular basis of β –TM, there are few review papers that consider a general view on the distribution of β –TM mutations in Iran. In the current review, common genetic defects identified in Iranian β –TM patients since 2005 to 2014 have been described. In addition, the prevalences and distributional trends of recognized mutations were discussed.  It was found that IVSII-1 (G>A) and IVSI-5 (G>C) were by far the most frequent mutations detected in Iranian patients. Other common reported mutations included FSC 8/9 (+G), IVS I-110 (G>A), FSC 36/37 (–T), IVSI-1 (G>A), IVSI (-25bp), and codon 44 (-C). In conclusion, it was found that molecular profile of β –TM is highly variable among different Iranian populations; in particular, it seems that ethnicity and intra-migration can be most important participating factors in controlling distributional patterns.

The Spectrum of β -thalassemia Mutations in Isfahan Province of Iran

Background: β-thalassemia is a common autosomal recessive disorder resulting from over 200 different mutations of beta globin genes. The aim of the present study was to identify the distribution and frequency of the most common β-thalassemia mutations among the population of Isfahan Province in central Iran. Methods: The data presented here were derived from a total of 114 β-thalassemia chromos...

Spectrum of α-thalassemia mutations in Qazvin Province, Iran

α-Thalassemia is a widespread inherited disease particularly prevalent in the middle East Asia population, including Iran. The aim of this study was to define the molecular spectrum and frequency of α-thalassemia mutations in prospective couples of Qazvin province. A total of 120,000 subjects were studied during 10 years (1998-2008). Individuals present with hypochromic and microcytic parameter...

The spectrum of β-thalassemia mutations in the Arab populations

The Arab countries encompass a wide region stretching from the Persian Gulf to the Atlantic Ocean. The Arab population is quite heterogeneous and has experienced various invasions and migrations throughout history. beta-thalassemia is endemic in all countries of the Arab world. Our review of the molecular basis of beta-thalassemia in various Arab countries reveals the presence of 52 mutations, ...
