Abstract
We characterized the molecular defect in a Swiss patient with a spontaneous beta-thalassemia mutation. Cloning and DNA sequencing of her beta-globin gene revealed a new frameshift mutation due to a single nucleotide deletion at codon 64 of the beta-globin gene. Restriction site polymorphism showed that the mutation arose on her paternal chromosome. Direct sequencing of a polymerase chain reaction amplified DNA segment showed absence of the lesion in both alleles of her father's beta-globin gene and confirmed the spontaneous nature of this mutation.
