Fragile x southern blot

WebMolecular diagnosis of fragile X syndrome is usually performed using Southern blot analysis of DNA digested with EcoRI. In the course of diagnostic studies, we observed that a specific EcoRI restriction site in the fragile X gene (FMR1) is sometimes refractory to digestion, generating additional fragments on a Southern blot suggestive of a full … WebThus, most of the described PCR protocols require subsequent Southern blot analysis and autoradiography. We present a novel PCR approach for the diagnosis of fragile X syndrome based on the methylation-sensitive conversion of C residues to U by bisulfite on single-strand DNA and subsequent amplification of the antisense strand with specific ...

WebMar 1, 2010 · Abstract. Background: Fragile X syndrome (FXS) is a trinucleotide-repeat disease caused by the expansion of CGG sequences in the 5′ untranslated region of the FMR1 (fragile X mental retardation 1) gene. Molecular diagnoses of FXS and other emerging FMR1 disorders typically rely on 2 tests, PCR and Southern blotting; … WebIn the routine laboratory, the use of Southern blotting is restricted to those diseases that require additional information the Southern blot can provide.
