Expandable DNA Repeat and Human Hereditary Disorders [PDF]
Background & Aims: Nearly 30 hereditary disorders in humans result from an increase in the number of copies of simple repeats in genomic DNA, including fragile X syndrome, myotonic dystrophy, Huntington’s disease, and Friedreich’s ataxia.

Variation within the Huntington's disease gene influences normal brain structure. [PDF]
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

Secondary structural choice of DNA and RNA associated with CGG/CCG trinucleotide repeat expansion rationalizes the RNA misprocessing in FXTAS. [PDF]
CGG tandem repeat expansion in the 5′-untranslated region of the fragile X mental retardation-1 (FMR1) gene leads to unusual nucleic acid conformations, hence causing genetic instabilities.

Stabilizing Effects of Interruptions on Trinucleotide Repeat Expansions in Saccharomyces cerevisiae [PDF]
In most trinucleotide repeat (TNR) diseases, the primary factor determining the likelihood of expansions is the length of the TNR. In some diseases, however, stable alleles contain one to three base pair substitutions that interrupt the TNR tract. The unexpected stability of these alleles compared to the frequent expansions of perfect TNRs suggested ...

Atomic resolution structure of CAG RNA repeats: structural insights and implications for the trinucleotide repeat expansion diseases [PDF]
CAG repeats occur predominantly in the coding regions of human genes, which suggests their functional importance. In some genes, these sequences can undergo pathogenic expansions leading to neurodegenerative polyglutamine (poly-Q) diseases.

Very Late-Onset Friedreich Ataxia with Laryngeal Dystonia [PDF]
Friedreich ataxia (FRDA) is an autosomal recessive neurodegenerative disorder characterized by progressive gait and limb ataxia, cerebellar, pyramidal and dorsal column involvement, visual defects, scoliosis, pes cavus and cardiomyopathy. It is caused by

Efficient CRISPR/Cas9-mediated editing of trinucleotide repeat expansion in myotonic dystrophy patient-derived iPS and myogenic cells. [PDF]
CRISPR/Cas9 is an attractive platform to potentially correct dominant genetic diseases by gene editing with unprecedented precision. In the current proof-of-principle study, we explored the use of CRISPR/Cas9 for gene-editing in myotonic dystrophy type-1
