Fig. 3From: Molecular characterization and mapping of glucose-6-phosphate dehydrogenase (G6PD) mutations in the Greater Mekong SubregionAllelic frequencies of G6PD Viangchan variant detected in samples collected from males in the GMS at the district level (a) and at the village or district level (b). Allelic frequencies were assessed by genotyping (PCR–RFLP or PCR-LDR-FMA). Circles in pane b are proportional to sample sizeBack to article page
