IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

The possible linkage between a gene causing heterocellular hereditary persistence of fetal hemoglobin (HPFH) and human non-alpha globin loci has been studied in a large Sardinian family. In this family a homozygous beta o-thalassemic patient was found, with an unusually mild form of this disease, which was ascribed to the co-existence of a gene causing heterocellular HPFH. DNA polymorphisms in the non-alpha globin cluster were analyzed by restriction enzyme digestion with HincII, HindIII and BamHI and with epsilon-, gamma-and beta-globin probes; the pattern of inheritance of these polymorphisms indicates that the HPFH gene is transmitted with one beta o-thalassemic gene in a single instance, with the second beta o-thalassemic gene in three instances and with a normal beta-globin gene in two cases. These data indicate that this HPFH gene is not linked to the non-alpha globin gene cluster, in contrast to previous observations with different HPFH genes, and suggest that this gene might code for diffusible substances acting, directly or indirectly, on gamma-globin gene expression.
