    Genetic analysis of human red cell phosphoglucomutase 1 (PGM1) in Egyptians revealed nine phenotypes. This PGM1 polymorphism can improve paternity testing accuracy, increasing exclusion probability.

    Area of Science:

    • Biochemistry
    • Human Genetics
    • Population Genetics

    Background:

    • Phosphoglucomutase 1 (PGM1) is a crucial enzyme in human red blood cells.
    • Genetic polymorphism in PGM1 influences its function and detection.
    • Understanding PGM1 allele frequencies is vital for population genetics and forensic applications.

    Purpose of the Study:

    • To investigate the genetic polymorphism of the human red cell phosphoglucomutase 1 (PGM1) in an Egyptian population.
    • To determine the allele frequencies of PGM1 genes in the studied samples.
    • To assess the utility of PGM1 polymorphism in paternity testing.

    Main Methods:

    • Isoelectric focusing in thin-layer polyacrylamide gel electrophoresis was employed.
    • Human red blood cell samples from 134 Egyptians were analyzed.

  • Phenotype and allele frequencies were calculated and compared to Hardy-Weinberg equilibrium.

    • Main Results:

    • Nine common PGM1 phenotypes were observed in the Egyptian population.
    • Allele frequencies for PGM1*1, PGM1*2, PGM2*1, and PGM2*2 were calculated.
    • The observed phenotype frequencies showed a good fit to Hardy-Weinberg equilibrium.

    Conclusions:

    • The PGM1 genetic system in Egyptians is polymorphic with specific allele frequencies.
    • The four-allele PGM1 system significantly enhances the power of exclusion in paternity testing.
    • This study provides valuable data for forensic science and population genetics in Egypt.
