A new frameshift β°‐thalassemia mutation (codons 27–28 +C) found in a Chinese family

Abstract
A new β°‐ halassemia mutation, a frameshift mutation with an insertion of a single cytosine nucleotide in codon 27–28, is described. The propositus, who is compound heterozygous for this mutation and the IVSII‐654 C→T β°‐thalassemia mutation, has the phenotype of severe β‐thalassemia major.
