    Transferrin subtyping revealed significant differences in allele frequencies among North and South Indian populations. A novel transferrin subtype, Tf Pangwala, was identified in the Pangwala community.

    Area of Science:

    • Genetics
    • Anthropology
    • Biochemistry

    Background:

    • Transferrin (Tf) plays a crucial role in iron transport.
    • Understanding Tf subtype distribution is vital for population genetics and disease association studies.
    • Previous studies have established TfC1 and TfC2 allele frequencies globally.

    Purpose of the Study:

    • To analyze transferrin subtyping and allele frequencies in six distinct Indian populations.
    • To compare Tf profiles between North and South Indian groups.
    • To identify any novel transferrin variants within these populations.

    Main Methods:

    • Transferrin subtyping was performed on blood samples from three North Indian (Pangwala, Gaddi-Bharmour, Gaddi-Kangra) and three South Indian (Koya, Konda Kammara, Lambadi) populations.

  • Phenotype and allele frequencies were calculated and analyzed.
  • Statistical comparisons were made with existing global Tf data.

    • Main Results:

    • Significant variations in transferrin phenotype and allele frequencies were observed across the six Indian populations.
    • All studied Indian populations exhibited distinct Tf allele frequencies compared to previously reported TfC1 and TfC2 frequencies.
    • A potential new transferrin subtype, designated Tf Pangwala, was identified in the Pangwala sample.

    Conclusions:

    • The genetic landscape of transferrin subtypes varies considerably within India.
    • Indian populations show unique Tf allele frequency profiles.
    • The discovery of the Tf Pangwala variant warrants further investigation and characterization.
