Large intronic expansions of the triplet-repeat sequence (GAA.TTC) cause transcriptional repression of the Frataxin gene (FXN) leading to Friedreich's ataxia (FRDA). We previously found that GAA-triplet expansions stimulate heterochromatinization in vivo in transgenic mice. We report here using chromosome conformation capture (3C) coupled with high-throughput sequencing that the GAA-repeat expa...
Expanded, non-coding RNAs can exhibit a deleterious gain-of-function causing human disease through abnormal interactions with RNA-binding proteins. Myotonic dystrophy (DM), the prototypical example of an RNA-dominant disorder, is mediated by trinucleotide repeat-containing transcripts that deregulate alternative splicing. Spliceopathy has therefore been a major focus of DM research. However, ch...
Genetics of the variability of normal and diseased brain structure largely remains to be elucidated. Expansions of certain trinucleotide repeats cause neurodegenerative disorders of which Huntington's disease constitutes the most common example. Here, we test the hypothesis that variation within the IT15 gene on chromosome 4, whose expansion causes Huntington's disease, influences normal human ...
Trinucleotide repeat disorders are a set of genetic disorders characterized by the expansion of certain genes of a segment of DNA that contains a repeat of three nucleotides, thus exceeding the normal stable threshold. These repeats in the DNA cause repeats of a specific amino acid in the protein sequence, and it is the repeated amino acid that results in a defective protein. Huntington's disea...
