    Summary

    Haptoglobin (Hp) phenotypes were consistent across Russian, Tatar, and Bashkir populations. However, the Hp 1-1 phenotype showed higher levels of certain liver enzymes, including alanine and aspartate aminotransferases.

    Area of Science:

    • Genetics
    • Biochemistry
    • Population Studies

    Background:

    • Haptoglobin (Hp) is a protein involved in various biological processes.
    • Understanding Hp phenotype distribution is crucial for population genetics and health studies.
    • Previous research has established different Hp phenotypes and their prevalence in various ethnic groups.

    Purpose of the Study:

    • To determine the distribution of Haptoglobin (Hp) phenotypes in Russian, Tatar, and Bashkir populations.
    • To investigate the relationship between Hp phenotypes and serum enzyme activities.
    • To compare Hp gene incidence with European populations.

    Main Methods:

    • Thin-layer polyacrylamide gel electrophoresis was used to determine Hp phenotypes.
    • Serum enzyme activities (alkaline phosphatase, gamma-glutamyl transpeptidase, alanine aminotransferase, aspartate aminotransferase, acid phosphatase) were measured.
    • Statistical analysis was performed to compare phenotype distributions and enzyme levels.

    Main Results:

    • Haptoglobin (Hp) phenotype distribution was similar across the studied populations: 13.4% Hp 1-1, 48% Hp 1-2, and 38.6% Hp 2-2.
    • The Hp1 gene incidence was 0.37, consistent with European populations.
    • Serum alkaline phosphatase and gamma-glutamyl transpeptidase activities were similar across all Hp phenotypes.
    • Alanine aminotransferase, aspartate aminotransferase, and acid phosphatase activities were significantly higher in the Hp 1-1 phenotype.

    Conclusions:

    • Haptoglobin (Hp) phenotype distribution is relatively uniform among Russians, Tatars, and Bashkirs.
    • The Hp1 gene incidence aligns with European population data.
    • Specific serum enzyme activities, particularly those related to liver function, differ between Haptoglobin (Hp) phenotypes, suggesting a potential biochemical link.
