A novel G6PD gene variant in a Chinese girl with favism.
Ontology highlight
ABSTRACT: Background
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzymopathy. The human G6PD gene is highly polymorphic, and over 200 mutations have been identified, many of which are associated with hemolytic anemia. Here, we analyzed the clinical genetics data of a Chinese girl with favism who developed acute hemolytic anemia after fava bean ingestion.Methods
The clinical genetics data of the proband who developed acute hemolytic anemia were collected and analyzed, and G6PD gene exons were sequenced in the proband and her family.Results
We reported for the first time a novel G6PD gene variant in a Chinese girl, which we named "G6PD Wuhan." This variant is localized exon 3 of the G6PD gene at genomic position 141G > C, that is a change from p.Lys47 to Asn. The bioinformatics analysis and protein modeling study indicated this variant may have negative effects on the enzyme activity of G6PD.Conclusions
Our results indicated that favism in the proband was caused by this novel heterozygous variant (c.141G > C) in G6PD. The variant in G6PD has implications for genetic counseling and could provide insights into the functional roles of G6PD mutations.
