β-globin gene inactivation by DNA translocation in γ β-thalassaemia.
Nature: international weekly journal of science , Volume 306 p. 662- 666
The beta-globin gene present on the deletion locus in a Dutch gamma beta-thalassaemic patient was found to be identical to the normal beta-globin gene with respect to DNA sequence and its transcription in HeLa cells. DNase I sensitivity and methylation experiments show that the affected beta-globin gene is present in an inactive configuration in vivo. This is the result of a translocation of a normally inactive locus next to the beta-globin gene on the affected chromosome, or the deletion of sequences which are normally required for the maintenance of the active state.
