Abstract
We attempted to characterize biochemically glucose-6-phosphate dehydrogenase (G6PD) variants in Iraqi individuals. Thus 758 healthy Iraqi males aged 18-60 years were randomly selected and 46 (6.1%) were G6PD deficient. Although the predominant non-deficient G6PD phenotype was G6PD B (92.6%), G6PD A+ was found in polymorphic frequency (1.3%). In the deficient group, 31 cases were fully characterized, including 17 cases with features consistent with G6PD Mediterranean variant, while 12 had other biochemical features and were labelled as non-Mediterranean variant. The remaining two deficient cases were characterized as G6PD A- variant. The presence of a significant number of non-Mediterranean variant was unexpected and may be related to the more heterogeneous background of the Iraqi people.
