Two new beta0-thalassemic mutations: a deletion (-CC) at codon 142 or overlapping codons 142-143, and an insertion (+T) at codon 45 or overlapping codons 44-45/45-46 of the beta-globin gene.
We report here two new beta(0)-thalassemic mutations. In the first case, a deletion of two nucleotides (-CC) at codon 142 was found in a French Caucasian woman. In the second case, an insertion of a single nucleotide (+T) at codon 45 was found in a Turkish girl. In both cases, no dominant thalassemia-like phenotype was observed.
