Agarose gel for RFLP analysis. Lane 1, 100bp ladder; Lanes 2-6, samples of B-thalassemia patients; Lanes 2 and 4-6, Xmn1 -/-; Lane 3, Xmn1 -/+.
Sequence alignment of (query) Xmn1 polymorphic β-thalassemia patient sample (GenBank KY927385) with the (subject) reported sequence of gamma globin gene retrieved from NCBI (GenBank: GU324926.1). Red outline indicates the transversion of C>T at position 158 bp upstream of the gamma-globin gene.
Sequence Chromatogram of Xmn1 polymorphic β-thalassemia patient at reference position 300 to 320. Black arrowhead indicates C>T transversion at 158 bp upstream of gamma globin gene.
Hypothetical illustration for increased gamma-globin gene expression by C>T polymorphism in the promoter region.
2 % agarose gel for RFLP analysis. Lane 1, contains 100bp ladder; Lanes 2-6, samples of β-Thalassemia patients; Lane 2, 418bp and 230bp of Xmn1 +/+ patient; Lanes 3-4, Xmn1 -/-; Lanes 5-6, no bands.
