Comments: The deletion spans 233.6 kb on the β-globin gene cluster, extending from the HBE1 gene to the olfactory receptor genes 3' to the HBB gene. (εγδβ)0-Thalassaemia was transmitted in an autosomal dominant manner with heterozygous deletion of genes across three generations. The deletion was also reported in a fetus that showed signs of developing anemia at 22 weeks of gestation. In total, three intrauterine transfusions were performed at weeks 23, 28, and 32. The baby was born at 38 weeks with no signs of anemia [PIMD: 39488721].
