title: Triplication (/alphaalphaalpha anti3.7) or deletion (-alpha3.7/) association in Argentinian beta-thalassemic carriers.
abstract: Prevalence of alpha gene triplication or deletion in beta-thalassemia carriers was studied in 109 unrelated individuals in Rosario, Argentina. In different populations -alpha(3.7) allele presents a higher prevalence than alphaalphaalpha(anti3.7); thus, alpha-thalassemia associated with beta-thalassemia is more frequently observed. Nevertheless, this event was detected in only one case (0.9%), while the association with alpha triplication was present in two subjects (1.8%).
