    Genotype-Phenotype Correlation of G6PD Mutations among Central Thai Children with G6PD Deficiency by Boonchai Boonyawat, Tim Phetthong, Nithipun Suksumek, Chanchai Traivaree

    Published 2021-01-01
    “…Only 1 in 27 heterozygous females (3.7%) had G6PD level in the affected male range (9 IU/ml.RBC) which is possibly explained by nonrandom X-chromosome inactivation. The correlation of genotypes, G6PD levels, and clinical phenotypes was not demonstrated in our study in which all of the included G6PD-deficient patients were presented with neonatal hyperbilirubinemia and acute hemolytic anemia, since the genotype-phenotype correlation is normally demonstrated in chronic nonspherocytic hemolytic anemia (CNSHA) G6PD-deficient individuals. …”
