ABSTRACT
<p><b>OBJECTIVE</b>To determine the molecular defects of beta-thalassemia intermedia in Guangdong Province and to provide basis for gene diagnosis and gene therapy of this disorder.</p><p><b>METHODS</b>DNA analysis of the alpha, beta and gamma globin genes was performed in 18 children with beta-thalassemia intermedia from Guangdong Province using polymerase chain reaction (PCR), microarray technique, Southern blot and direct sequencing.</p><p><b>RESULTS</b>Of the 18 patients,one was identified as the homozygote of TATA box-28 (A-->G) change, one as the homozygote of betaE26 (G-->A) mutation, ten as compound heterozygotes of TATA box- 28 (A-->G) mutation with other beta-globin mutations, two as compound heterozygotes of betaE26 (G-->A ) mutation with other beta globin mutations, and four as double heterozygotes for beta globin and alpha globin mutations including -SEA and -alpha(4.2).</p><p><b>CONCLUSIONS</b>The molecular defects of beta- thalassemia intermedia in Guangdong Province were highly heterogeneous and its spectrum was different from the reports from other provinces of China.</p>
