Abstract

Friedreich ataxia (FRDA) is an autosomal recessive disorder characterized by neurodegeneration and cardiomyopathy. The presence of a GAA trinucleotide repeat expansion in the first intron of the FXN gene results in the inhibition of gene expression and an insufficiency of the mitochondrial protein frataxin. We previously generated BAC-based transgenic mice containing an FXN-EGFP genomic reporter construct in which the EGFP gene is fused in-frame immediately following the final codon of exon 5a of the human FXN gene. These transgenic mice were mated with mice heterozygous for a knockout mutation of the murine Fxn gene, to generate mice homozygous for the Fxn knockout mutation and hemizygous o..
