Abstract
There are scarce data about the glucose-6-phosphate dehydrogenase (G6PD) variants in Haiti to guide public health guidelines. In this study, we investigated the prevalence of the G6PD mutations related to the A- variant. We found an allelic frequency of 35.8% for the A376G mutation and of 12.2% for the G202A mutation. We also found a novel C370T mutation concomitant with the A376G mutation in one study participant. The G680T and T968C mutations were not found. The G6PD deficient variant A202 (A376G and G202A mutations) has appreciable prevalence in Haiti (16.6%), consideration is warranted when using drugs such as primaquine, which may trigger hemolytic anemia among G6PD-deficient people.
