DEL LUJAN ACOSTA, Irma et al. Erythrocyte glucose-6-phosphate dehydrogenase deficiency in Rosario. Acta bioquím. clín. latinoam. [online]. 2012, vol.46, n.3, pp.359-363. ISSN 0325-2957.

Enzymatic activity (EA) of erythrocyte glucose-6-phosphate dehydrogenase (G6PD) and electrophoretic mobility (EM) have been studied in a population of males and females in the city of Rosario and its area of influence. To determine EA, the Glock and McLean kinetic technique was used. Electrophoretic mobility assay was performed by M.C. Rattazzi and L.C. Bernini technique in cellulose acetate gel. Results demonstrated that the EA values in normal individual are independent of age, sex and hemoglobin values. The normal values of EA were: 8.1±1.4 IU of G6PD/g Hb. There were no significant differences in different age groups studied regarding healthy adults, except for neonatal group that yielded a significant EA increase which is directly related to the physiological characteristics of newborn erythrocytes. Two patients out of 686 individuals bearing G6PD deficiency were detected, corresponding to 0.3% prevalence. The electrophorectic mobility pattern was 98% (n: 672) for G6PD B, and 2% (n: 14) for G6PD A fast mobility variant.

Keywords : Glucose-6-phosphate dehydrogenase deficiency; Electrophoretic mobility.
