  • Title: Detection of a rare mutation in an Iranian family: codons 37/38/39 (7 bp deletion).
    Author: Zadeh-Vakili A, Eshghi P.
    Journal: Hemoglobin; 2009; 33(6):523-7. PubMed ID: 19958201.
    Abstract:
    We recently found a rare beta(0)-thalassemia (beta(0)-thal) mutation, namely codons 37/38/39 (-GACCCAG), in a consanguineous family from southeast Iran. The first cousin couple was heterozygous for the mutation. They had a healthy 4-year-old daughter and were referred to us for prenatal diagnosis at 6 weeks gestation in the second pregnancy. The fetus, based on results of sequencing of the beta-globing gene, was homozygous for the same mutation. Results of amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) on detection of this 7 bp deletion, and also restriction fragment length polymorphism (RFLP) analysis confirmed the homozygosity of the fetus.
