Restoration of correct splicing of thalassemic beta-globin pre-mRNA by modified U1 snRNAs.

Abstract excerpt

The T-->G mutation at nucleotide 705 in the second intron of the beta-globin gene creates an aberrant 5' splice site and activates a 3' cryptic splice site upstream from the mutation. As a result, the IVS2-705 pre-mRNA is spliced via the aberrant splice sites leading to a deficiency of beta-globin mRNA and protein and to the genetic blood disorder thalassemia. We have shown previously that in cell culture models...
