Abstract

Objective: Identification of glucose-6-phosphate dehydrogenase (G6PD) mutation in Muong ethnic patients with G6PD deficiency. Methods: 43 Muong ethnic patients were diagnosed with G6PD deficiency at National Pediatrics hopspital; PCR and direct sequencing were used to identify mutation in G6PD gene. Results:  41/43 patients were detected to have mutation in G6PD gene with 7 types of mutation, in which the mutation with  highest rate was Union (c.1360C>T) with 46.5%, following were Canton (c.1388G>A) and Viangchan (c.871G>A) with  20.9% and 16.3% respectively. We found Kaiping (c.1388G>A) mutation with 2 cases;  Chinese-5 (c.1024C>T), Coimbra (c.592C>T) and Mediterranean (c.563C>T) each mutation for one case. Silent mutation at 1311 location were found with 9 cases.
