Glucose-6-phosphate dehydrogenase deficiency in South Vietnamese
Human Heredity
|January 1, 1980
Insights
Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency was found in 1.31% of South Vietnamese males. Three enzyme variants, including Mahidol and Canton, were identified in deficient individuals.
Area of Science:
- Biochemistry
- Genetics
- Hematology
Background:
- Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is a common inherited red blood cell disorder.
- Understanding the prevalence and genetic variants of G-6-PD deficiency is crucial for public health in endemic regions.
Purpose of the Study:
- To determine the incidence of erythrocyte G-6-PD deficiency in South Vietnamese males.
- To identify and characterize the genetic variants of G-6-PD in deficient individuals.
Main Methods:
- Screening of erythrocyte G-6-PD levels in a cohort of South Vietnamese males.
- Biochemical characterization of partially purified erythrocyte G-6-PD enzyme from deficient subjects.
Main Results:
- An overall incidence of 1.31% for G-6-PD deficiency was observed (7 out of 534 males).
- Six deficient males were analyzed, revealing three distinct G-6-PD variants: Mahidol (3 individuals), Canton (2 individuals), and Long Xuyen (1 individual).
Conclusions:
- The study establishes the prevalence of G-6-PD deficiency in the studied South Vietnamese population.
- The identification of specific G-6-PD variants (Mahidol, Canton, Long Xuyen) provides insight into the genetic landscape of this deficiency in the region.
Abstract:
7 out of 534 South Vietnamese males showed erythrocyte glucose-6-phosphate dehydrogenase (G-6-PD) deficiency, giving a 1.31% incidence of G-6-PD deficiency. Partially purified erythrocyte enzyme was studied in 6 of the 7 G-6-PD deficient males. Three variants were found: G-6-PD Mahidol (3), Canton (2), and Long Xuyen (1).
