Frequency of human Aγ75Thr globin chain in a population from Tunisia

Abstract
Cord blood samples, collected at Sousse and Monastir, from Tunisian newborns were focused on a thin layer of agarose in order to detect the carriers of the Aγ75Thr chain (Aγ chain bearing a replacement Ile→Thr at position 75). Nineteen individuals (10%) were positive for this variant. The frequency of the Aγ75Thr gene in the Tunisian population (0.050) is compared with that of various ethnic populations.
