Insights
Glucose-6-phosphate dehydrogenase (G6PD) deficiency was screened in 296 males from Hainan Island
Area of Science:
- Biochemistry
- Genetics
- Public Health
Background:
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common inherited red blood cell disorder.
- Prevalence varies significantly across different ethnic groups and geographic regions.
- Understanding G6PD deficiency in diverse populations is crucial for public health initiatives.
Purpose of the Study:
- To investigate the prevalence of G6PD deficiency among Li, Miao, and Hui ethnic groups in Hainan Island, China.
- To characterize identified G6PD variants.
- To identify potential novel G6PD variants.
Main Methods:
- Screening of 296 healthy males from three ethnic groups for G6PD deficiency.
- Biochemical characterization of G6PD variants from deficient individuals.
- Genetic analysis to identify and name new variants.
Main Results:
- A total of 19 individuals with G6PD deficiency were identified across the three groups.
- Prevalence rates were 6.47% in Li, 16.67% in Miao, and 1.83% in Hui.
- Three distinct G6PD variants were characterized, including a novel variant tentatively named G6PD Huizu-Sanya.
Conclusions:
- G6PD deficiency exhibits varying prevalence among the studied ethnic groups in Hainan.
- The identification of distinct and potentially novel G6PD variants highlights the genetic diversity of the deficiency.
- Further research is warranted to understand the clinical implications of these variants in the local population.
Abstract:
A total of 296 healthy males belonging to three national minority groups, Li, Miao and Hui, in Hainan Island, China, were screened for G6PD deficiency. 9 out of 139 Li (6.47%), 8 out of 48 Miao (16.67%), and 2 out of 109 Hui (1.83%) individuals were found to be G6PD deficient. Of these 19 variant samples, three were subjected to G6PD characterization and found to be different from each other. They were considered to be G6PD Miaozu-Baisha, G6PD Qingyuan, and a new variant tentatively named G6PD Huizu-Sanya.
