Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzymopathy and in Sub-Saharan Africa, is a significant cause of infection- and drug-induced hemolysis and neonatal jaundice. Our goals were to determine the prevalence of G6PD deficiency among Nigerian children of different ethnic backgrounds and to identify predictors of G6PD deficiency by analyzing vital signs and h...

Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway (PPP) that plays an important role in protecting cells from oxidative damage by producing NADPH and reduced glutathione. G6PD deficiency is considered one of the most common genetic disorders present in the X chromosome and is the most common of enzymopathic red blood cell disorder. Angiotensin converting enz...

AIMS To present the strategy of identifying the molecular variants of G6PD detected in neonatal screening (NS). MATERIAL AND METHODS We present a series of incident cases of newborns positive for G6PD deficiency detected in NS. From nuclear DNA with the methodology of real-time PCR we sought molecular G6PD variants: G202A, A376G, T968C and C563T. RESULTS Of a total of 21,619 neonates, 41 ca...

Reactive oxygen species (ROS)-mediated cell injury contributes to the pathophysiology of cardiovascular disease and myocardial dysfunction. Protection against ROS requires maintenance of endogenous thiol pools, most importantly, reduced glutathione (GSH), by NADPH. In cardiomyocytes, GSH resides in two separate cellular compartments: the mitochondria and cytosol. Although mitochondrial GSH is m...

To establish the neonatal screening method of glucose-6 phosphate dehydrogenase (G6PD) deficiency, G6PD activity was measured using the fluorescence spot test (FST) using dried blood samples on filter paper. The G6PD/6PGD rate test of venous blood samples was further performed for confirmation. The positive G6PD deficiency rate was 4.2% and its detection rates were 3.7% for all neonates and 5.2...

The most common enzyme defect in humans is glucose-6-phosphate dehydrogenase (G6PD) deficiency, which affects more than 400 million people. G6PD shunts glucose into the pentose phosphate pathway (PPP) to generate nucleotides and reducing potential in the form of NADPH. In this issue, Wang et al (2014) show that G6PD activity is post-translationally regulated by SIRT2, a cytoplasmic NAD-dependen...

We performed DNA analysis on cord blood samples of 128 Chinese male neonates diagnosed as G6PD deficiency in Hospital Universiti Kebangsaan Malaysia by a combination PCR-restriction enzyme digest technique, Single Stranded Conformation Polymorphism analysis and DNA sequencing. We found 10 different G6PD-deficient mutations exist. The two commonest alleles were G6PD Canton 1376 G>T (42.3%) and K...

Glucose-6-phosphate dehydrogenase (G6PD) is a key regulatory enzyme in the pentose phosphate pathway which produces nicotinamide adenine dinucleotide phosphate (NADPH) to maintain an adequate reducing environment in the cells and is especially important in red blood cells (RBC). Given its central role in the regulation of redox state, it is understandable that mutations in the gene encoding G6P...

BACKGROUND This study aimed to evaluate the prevalence and alteration of hematological parameters in malaria patients with a glucose-6-phosphate dehydrogenase (G6PD) deficiency, in the western region of Thailand, an endemic region for malaria. METHODS Data about patients with malaria hospitalized between 2013 and 2015 were collected. Clinical and sociodemographic characteristics such as age a...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency, a recessive X-linked trait, is the most common enzyme deficiency in the world. The most devastating clinical consequence of this deficit is severe neonatal jaundice, which results in sensorineural deficit, and severe haemolytic anemia. However, patients may be asymptomatic. The most common clinical sign is hyperbilirubinemia (h↑), that is als...
