Molecular epidemiological investigation of G6PD deficiency in Yangjiang region, western Guangdong province. Front Genet 2024; 14:1345537.

Abstract
Objectives: The prevalence of G6PD deficiency has not been reported in Yangjiang, a western city in Guangdong province. This study aims to investigate the molecular characteristics of G6PD deficiency in this region. Methods: Blood samples were collected from adults at a local hospital to screen for G6PD deficiency. The deficient samples were subjected to further analysis using PCR and reverse dot blot to determine the specific G6PD variants. Results: Among the 3314 male subjects, 250 cases of G6PD deficiency were found using the G6PD enzyme quantitative assay, resulting in a prevalence of 7.54% (250/3314) in the Yangjiang region. The prevalence of G6PD deficiency in females was 3.42% (176/5145). Out of the 268 cases of G6PD deficiency tested for G6PD mutations, reverse dot blot identified 20 different G6PD variants. The most common G6PD variant was c.1388G>A (81/268), followed by c.1376G>T (48/268), c.95A>G (32/268), c.1024C>T (9/268), c.392G>T (7/268), and c.871G>A/c.1311C>T (6/268). It was observed that c.871G>A was always linked to the polymorphism of c.1311C>T in this population. Conclusion: This investigation into G6PD deficiency in this area is expected to significantly improve our understanding of the prevalence and molecular characterization of this condition.

Lin F, Lou ZY, Xing SY, Zhang L, Yang LY. The gene spectrum of glucose-6-phosphate dehydrogenase (G6PD) deficiency in Guangdong province, China. Gene 2018; 678:312-317. [PMID: 30077011 DOI: 10.1016/j.gene.2018.07.068] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 07/07/2018] [Accepted: 07/26/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND G6PD deficiency presents a higher incidence rate in southern China. Many variants of G6PD resulted from point mutations in the G6PD gene, which lead to decrease of enzyme activity. The objective of this study was to analyze the genotype of G6PD deficiency in four regions of Guangdong province. METHODS Genotype of 1756 cases with G6PD deficiency was identified by reverse dot blotting (RDB). Unidentified Genotype of the samples was further ascertained by direct DNA sequencing. RESULTS 34 genotype were found in 1756 cases of G6PD deficiency, Canton (c.1376 G>T) and Kaiping (c.1388 G>A) were the most common variants, accounting for more than 63% of G6PD deficiency individuals, and the following mutations were Gaohe (c.95 A>G), Chinese-5 (c.1024 C>T) and Chinese-4 (c.392 G>T). Two rare mutations Orisa (c.131 C>G) and IVS-5 637/638 T del have been discovered in this study. In addition, c.1311 C>T/IVS-1193 T>C polymorphism had a relatively high frequency in the normal G6PD individuals. CONCLUSIONS This study provided detailed genotypes of G6PD deficiency in Guangdong, and would be valuable for diagnosis and research of G6PD deficiency in this area.
