  • Title: The pattern of thalassemia in Naples.
    Author: Pepe G, Lupi L, Mastrobuono A, Carestia C, Lania A, Luzzatto L.
    Journal: Birth Defects Orig Artic Ser; 1982; 18(7):177-84. PubMed ID: 7159727.
    Abstract:
    1. The expected number of patients with Cooley anemia in Naples, as predicted from heterozygote frequencies, is about 300 which is more than that found from hospital statistics. 2. Considering the presence of at least two beta-thalassemic alleles and the coexistence of a significant incidence of the Lepore gene in the population of the area surrounding Naples (the maximum incidence is thought to be in the neighboring province of Caserta), there are at least 6 different genotypes (3 true homozygotes and 3 genetic compounds) that can give rise to clinically important thalassemia syndromes, ranging from thalassemia intermedia to classic Cooley anemia. 3. Since an alpha-thalassemic gene is also present at polymorphic frequency in this population, this gene may coexist by random assortment in subjects who also have a beta-thalassemia syndrome, thus accounting for part of the variability of globin gene expression. 4. It is remarkable that 2 brothers homozygous for Hb Lepore present differences in the non-alpha/alpha ratio. The clinical differences could be explained by the gamma/alpha mRNA ratio close to 1 in one of them.
