Identification of two novel β°‐thalassemia mutations in a filipino family: Frameshift codon 67 (− TG) and a β‐globin gene deletion

The frequency of beta-thalassemia alleles among Filipinos is estimated to be 0.02, although little is known about the actual mutations represented in this population. Here, we describe a Filipino family in which a child has severe beta-thalassemia major. Molecular studies of the family revealed that the proband is a compound heterozygote for two previously unreported beta zero-thalassemia alleles: a frameshift mutation (-TG) at codon 67 and a …
