Abnormal hemoglobins in Northwestern Mexico

B Ibarra, G Vaca, E Franco-Gamboa

    Acta Anthropogenetica
    |January 1, 1982
    PubMed
    Summary

    Screening of 9,929 individuals in Northwestern Mexico revealed low frequencies of abnormal hemoglobins (Hbs). The findings indicate that these genetic traits do not pose a significant public health concern in the region.

    Area of Science:

    • Hematology
    • Genetics
    • Public Health

    Background:

    • Abnormal hemoglobins (Hbs) are genetic variations affecting red blood cells.
    • Understanding Hb prevalence is crucial for assessing regional health burdens.

    Purpose of the Study:

    • To determine the frequency of abnormal hemoglobins (Hbs) in Northwestern Mexico.
    • To characterize rare Hb variants identified in the population.

    Main Methods:

    • Blood samples from 9,929 individuals were analyzed.
    • Assays were performed to detect various alpha-thalassemia, beta-thalassemia, HbS, HbC traits, and rare abnormal Hbs.

    Main Results:

    • Low frequencies (0-0.45%) of alpha-thal, beta-thal, beta S, and beta C traits were observed.

  • Eight rare abnormal Hbs were characterized, including Hb Riyadh, Hb J Georgia, Hb Fannin-Lubbock, Hb Chiapas, and Hb Tarrant.
  • Eleven rare abnormal Hbs were detected in total.

    • Conclusions:

    • Abnormal hemoglobins do not represent a major public health issue in Northwestern Mexico.
    • The observed genetic variations suggest significant ethnologic heterogeneity within the studied population.
