β-Globin gene inactivation by DNA translocation in γβ-thalassaemi

β-Globin gene inactivation by DNA translocation in γβ-thalassaemi The β-globin gene present on the deletion locus in a Dutch γβ-thalassaemic patient was found to be identical to the normal β-globin gene with respect to DNA sequence and its transcription in HeLa cells. DNase I sensitivity and methylation experiments show that the affected β-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 β-globin gene on the affected chromosome, or the deletion of sequences which are normally required for the maintenance of the active state. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals

Abstract

The β-globin gene present on the deletion locus in a Dutch γβ-thalassaemic patient was found to be identical to the normal β-globin gene with respect to DNA sequence and its transcription in HeLa cells. DNase I sensitivity and methylation experiments show that the affected β-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 β-globin gene on the affected chromosome, or the deletion of sequences which are normally required for the maintenance of the active state.
