molecular identification of g6pd chatham (1003 g>a) in north-west iran

Background and objective: glucose 6-phosphate dehydrogenase (g6pd) deficiency is one of the most common human diseases with approximately 400 million people affected worldwide. g6pd chatham is caused by 1003 g>a mutation leads to a severe enzymatic deficiency. the aim of the present study is to investigate the frequency rate of the chatham mutations in the population of the north-west of iran. material and method: in this study, by rapid genomic dna extraction (rgde) method, from 90 peripheral blood samples of unrelated male and female patients with genetic deficiency of g6pd, dna was extracted and after digestion by bstx1 enzymes, in order to search for chatham mutation, they were analyzed by means of pcr-rflp and sequencing methods. result: according to the results, chatham mutation was observed in 10 samples (11.11%). conclusion: this study showed that g6pd chatham (1003 g>a) mutation is the second common mutation, after mediterranean (563c>t), in the population of the north-west of iran. further studies are recommended to identify the mutation type of other varieties.
