  • Title: Rapid detection of common Chinese glucose-6-phosphate dehydrogenase (G6PD) mutations by denaturing gradient gel electrophoresis (DGGE).
    Author: Lam VM, Huang W, Lam ST, Yeung CY, Johnson PH.
    Journal: Genet Anal; 1996 Mar; 12(5-6):201-6. PubMed ID: 8740837.
    Abstract:
    We describe here the use of denaturing gradient gel electrophoresis (DGGE) to detect the most common Chinese glucose-6-phosphate dehydrogenase (G6PD) variants, which are the single point mutations: G-->T at nt 1376, G-->A at 1388 both in exon 12 and A-->G at nt 95 in exon 02. In each case, the mutant allele resolves well from the normal allele(s). The distinct heteroduplex bands are characteristic of a particular genotype suggesting that this feature is very useful for identifying all heterozygous carriers for this and other X-linked diseases. When the analysis is extended to other exons, DGGE scans the gene and coupled with direct sequencing, it leads to the identification of new G6PD variation(s). With this approach, we identified a mutation in exon 9 which had not been reported in Hong Kong. Since DGGE can rapidly screen many unknown samples in one gel, this approach could be used to diagnose these G6PD mutations and to identify the at-risk for counselling.
