Enzyme polymorphisms and haemoglobin variants in Greeks.

P Schneider, R Aanthakrishnan, H Walter

    Humangenetik
    |January 1, 1975
    PubMed
    Summary

    This study analyzed enzyme polymorphisms and hemoglobin variants in 219 Greek blood donors. Gene frequencies for key enzymes and hemoglobin types were determined, with no variation found in others.

    Area of Science:

    • Population genetics
    • Human genetics
    • Biochemical genetics

    Background:

    • Genetic diversity studies are crucial for understanding population history and health.
    • Enzyme polymorphisms and hemoglobin variants are common genetic markers used in population studies.

    Purpose of the Study:

    • To determine the gene frequencies of various enzyme polymorphisms and hemoglobin variants in a Greek population.
    • To identify genetic variations within a sample of Greek blood donors.
    • To discuss the population genetical implications of the observed genetic markers.

    Main Methods:

    • Blood samples from 219 non-related Greek donors were analyzed.
    • Typing was performed for several enzyme polymorphisms (e.g., PGM, PGD, AK) and hemoglobin variants (HbA, HbS).
    • Gene frequencies were calculated for observed variants.

    Main Results:

    • Observed gene frequencies: PGM (pa=0.201, pb=0.701, pc=0.098), PGD (PGDA=0.985, PGDc=0.015), AK (AK1=0.942, AK2=0.058), Hemoglobin (HbA=0.988, HbS=0.012).
    • No polymorphic variation was detected for Lactate Dehydrogenase (LDH), supernatant Medium-chain-length fatty acids Dehydrogenase (s-MDH), Phosphoglucose Isomerase (PHI), or Superoxide Dismutase (SOD).

    Conclusions:

    • The study provides baseline genetic data for specific enzyme and hemoglobin variants in the Greek population.
    • The observed gene frequencies contribute to the understanding of human genetic diversity in the region.
    • Further population genetics research can build upon these findings.
