Glucose-6-phosphate dehydrogenase deficiency does not result from mutations in the promoter region of the G6PD gene

Abstract

In this study, we investigated whether glucose-6-phosphate dehydrogenase (G6PD) promoter mutations are responsible for G6PD deficiency. We analysed the G6PD proximal promoter and the 5′ untranslated region (UTR) in 65 G6PD-deficient individuals, in which no mutations have been found in the G6PD gene coding sequences, using a nonradioactive polymerase chain reaction/single-strand conformation polymorphism (PCR/SSCP) analysis. We identified no sequence variations in the G6PD core promoter or in the 5′ UTR of these G6PD-deficient individuals, which indicates that G6PD deficiency is not associated with promoter mutations in the G6PD locus. © 2003 Wiley-Liss, Inc.
