Erythrocyte glutathione reductase polymorphism in a Sudanese population
Abstract:
414 random samples of blood collected from unrelated male blood donors in Khartoum were analysed for erythrocytic glutathione reductase (GSR) phenotypes in relation to glucose-6-phosphate dehydrogenase (G6PD) and haemoglobin types by starch gel electrophoresis. The overall frequencies of GSR1 and GSR2 were found to be 0.9493 and 0.507, respectively. The frequency of GSR0 was very low (0.0241). The frequency of GSR2 was higher in G6PD-deficient subjects compared to normal subjects. GSR phenotypes were not related to the haemoglobin types. However, there was an excess of GSR0 in subjects with haemoglobin AS.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase
Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters
Drug toxicity: Idiosyncratic Reactions
Sulfur Assimilation
