A total of 362 males from various regions of Papua New Guinea were screened for red cell glucose-6-phosphate dehydrogenase (G6PD) activity. Twenty-six G6PD deficient individuals were identified. Biochemical characterization of G6PD purified from these subjects has revealed 13 new variants and several copies of previously described forms of G6PD. This study illustrates the extreme heterogeneity of G6PD deficiency among the people of Papua New Guinea.
Four new G6PD variants have been characterized in individuals from Papua New Guinea. This study demonstrates that the previously reported Markham variant and the newly characterized Salata variant may be widely distributed in Papua New Guinea. Th data presented here together with those of previously published studies demonstrate a degree of heterogeneity of G6PD deficiency that is much higher than that in other regions of the world where G6PD deficiency is common.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
