    Summary

    This study analyzed blood group antigen frequencies in 400 Gabonese individuals across six ethnic groups. Findings align with known antigen limits, noting rare phenotypes like S--s U-- and Lu(a--b--).

    Area of Science:

    • Genetics
    • Anthropology
    • Immunology

    Background:

    • Blood group antigen distribution varies significantly across global populations.
    • Understanding these variations is crucial for transfusion medicine and population genetics.
    • Previous studies have provided limited data on Gabonese ethnic groups.

    Purpose of the Study:

    • To determine the frequencies of various blood group antigens in a Gabonese population.
    • To compare these frequencies with data from geographically proximate African populations.
    • To identify and report any rare or unusual blood group phenotypes observed.

    Main Methods:

    • Serological investigation of blood samples from 400 individuals.
    • Categorization of participants into six distinct ethnic groups.
    • Statistical calculation and comparison of antigen frequencies.

    Main Results:

    • Frequencies for ABO, Lewis, Rhesus, Kell, Duffy, Kidd, MNSs, P, and Lutheran systems were determined.
    • Observed frequencies fall within established ranges for most antigens.
    • Rare phenotypes identified include 12 S--s U--, 1 Lu(a--b--), 2 I negative, and 7 Sc: --1.

    Conclusions:

    • The blood group antigen profile of the studied Gabonese population is largely consistent with existing data for African populations.
    • The identification of rare phenotypes highlights the genetic diversity within the region.
    • Further research is warranted to fully characterize blood group diversity in Central Africa.
