E-GEOD-7847 - Genotyping of human thalassemia patients reveals that the evolution of human beta-thalassemia major from minor is associated with paternal uniparental isodisomy of chromosome 11p15

β-thalassemia major can be caused by homozygous mutations of the HBB gene, most of the cases are inherited from parents who both have β-thalassemia minor. Herein, we show that a mosaic paternal uniparental isodisomy of chromosome 11p14.3-15.5 is associated with β-thalassemia major in a patient with β-thalassemia minor-that evolved to β-thalassemia major. From this case, we suggest that analysis of HBB gene for non-hematopoietic tissues should be performed in late-onset β-thalassemia major patients. Experiment Overall Design: This study is to evaluate the cause of delay-onset β-thalassemia major in our patient. Patients peripheral blood, hair follicle, and oral mucosa, and her parents pripheral blood samples were analyzed.
