ABSTRACT: Most of the beta-thalassemia cases in Bangladesh are caused by 5-7 common mutations in the
beta-globin gene. The present study reports a rare mutation in compound heterozygosity with a common
mutation in beta-globin gene of a thalassemic patient first time in Bangladesh. A Bangladeshi individual, born to
a family of carrier mother and normal father was diagnosed with abnormal hemoglobin electrophoresis result.
Sequencing analysis revealed the presence of a rare mutation caused by the deletion of a thymine at c.46 of ï
