Genetic variations in transferrin (TF) were studied in Libyans. TF*C1 and TF*C2 were the most common alleles, with a 19.2% exclusion rate for paternity testing.

Area of Science:

  • Human Genetics
  • Population Genetics
  • Biochemistry

Background:

  • Transferrin (TF) is a key iron transport protein.
  • Genetic polymorphism of TF influences its function and distribution.
  • Understanding TF allele frequencies is crucial for population genetics and forensic applications.

Purpose of the Study:

  • To investigate the genetic polymorphism of transferrin (TF) in a Libyan population.
  • To determine the allele frequencies of different TF phenotypes.
  • To assess the utility of TF polymorphism in paternity testing.

Main Methods:

  • Ultrathin layer polyacrylamide gel isoelectric focusing (PAGIF) was employed.
  • Coomassie brilliant blue R250 staining was used for visualization.

  • Analysis was performed on 110 unrelated Libyan individuals.

    • Main Results:

    • Five common and one rare TF phenotypes were identified.
    • Estimated allele frequencies: TF*C1 = 0.7455, TF*C2 = 0.2091, TF*C3 = 0.0409, TF*D = 0.0045.
    • A theoretical exclusion rate of 19.2% was calculated for disputed paternity cases.

    Conclusions:

    • The study provides valuable data on TF genetic polymorphism in Libyans.
    • The observed allele frequencies highlight the genetic diversity within the population.
    • TF polymorphism demonstrates significant potential for forensic and paternity investigations in this demographic.
