Abstract:
Objective To explore the genotype of patients with glucose-6-phosphate dehydrogenas(G6PD)deficiency in Dong-guan and provide the basis for the clinical diagnosis and prevention.Methods The clinical data of patients who took G6PD activity screening in the hospital were collected from January 2011 to December 2013,the G6PD/6PGD ratios were recorded.469 patients with positive G6PD/6PGD ratio were randomly enrolled in the study,whose mutations were detected by reverse dot blot(RDB)as-say.Results During this period,we measured G6PD activity of 16 464 cases by G6PD/6PGD ratios,there were 672 positive cases, the positive rate was 4.08%.Randomly selected 469 positive samples,detected their genotye by RDB assay.We detected 173 cases of G1376T,141 cases of G1388A,82 cases of A95G,60 cases of G871A,23 cases of G392T,14 cases of C1024T.In addition to that, we also found some rare mutations,such as 6 cases of C1004T,2 cases of T517C,1 cases of C1360T.65 cases of C1311T gene poly-morphism and 96 cases of dual gene mutations were detected.Conclusion The incidence of G6PD deficiency is high and the gene mutation types in Dongguan are both representative for Chinese population and with local heterogeneity.The study on gene muta-tions of G6PD deficiency is benefit for diagnosis and prevention.
