Resumen
Dynamic mutations in some human genes containing trinucleotide repeats are associated with severe neurodegenerative and neuromuscular disorders—known as Trinucleotide (or Triplet) Repeat Expansion Diseases (TREDs)—which arise when the repeat number of triplets expands beyond a critical threshold. While the mechanisms causing the DNA triplet expansion are complex and remain largely unknown, it is now recognized that the expandable repeats lead to the formation of nucleotide configurations with atypical structural characteristics that play a crucial role in TREDs.

Resumen
ABSTRACT Despite substantial progress in understanding the mechanism by which expanded CTG/CAG trinucleotide repeats cause neurodegenerative diseases, little is known about the basis for repeat instability itself. By taking advantage of a novel phenomenon, we have developed a selectable assay to detect contractions of CTG/CAG triplets. When inserted into an intron in the APRT gene or the HPRT minigene, long tracts of CTG/CAG repeats (more than about 33 repeat units) are efficiently incorporated into mRNA as a new exon, thereby rendering the encoded protein nonfunctional, whereas short repeat t

Resumen
Trinucleotide repeat expansion disorders (TREDs) are a group of dominantly inherited neurological diseases caused by the expansion of unstable repeats in specific regions of the associated genes. Expansion of CAG repeat tracts in translated regions of the respective genes results in polyglutamine- (polyQ-) rich proteins that form intracellular aggregates that affect numerous cellular activities. Recent evidence suggests the involvement of an RNA toxicity component in polyQ expansion disorders, thus increasing the complexity of the pathogenic processes.

Resumen
Abstract Tandem repeats of various trinucleotide motifs are frequent entities in transcripts, and RNA structures formed by these sequences depend on the motif type and number of reiterations. The functions performed by normal triplet repeats in transcripts are poorly understood, but abnormally expanded repeats of certain types trigger pathogenesis in several human genetic disorders known as the triplet repeat expansion diseases (TREDs). The diseases caused by expanded non-coding CUG and CGG repeats in transcripts include myotonic dystrophy type 1 and fragile X-associated tremor ataxia syndrome

Resumen
Trinucleotide repeat (TNR) expansions cause nearly 20 severe human neurological diseases which are currently untreatable. For some of these diseases, ongoing somatic expansions accelerate disease progression and may influence age of onset. This new knowledge emphasizes the importance of understanding the protein factors that drive expansions. Recent genetic evidence indicates that the mismatch repair factor MutSβ (Msh2-Msh3 complex) and the histone deacetylase HDAC3 function in the same pathway to drive triplet repeat expansions.

Resumen
AbstractTriplet repeat diseases (TRDs) are caused by pathogenic expansions of trinucleotide sequence repeats within coding and non-coding regions of different genes. They are typically progressive, very disabling and frequently involve the nervous system. Currently available symptomatic therapies provide modest benefit at best. The development of interventions that interfere with the natural history of these diseases is a priority. A common pathogenic process shared by most TRDs is the presence of toxicity from the messenger RNA or protein encoded by the gene harboring the abnormal expansion.

ABSTRACT:Since the early 1990s, DNA triplet repeat expansions have been found to be the cause in an ever increasing number of genetic neurologic diseases. A subset of this large family of genetic diseases has the expansion of a CAG DNA triplet in the open reading frame of a coding exon. The result of this DNA expansion is the expression of expanded glutamine amino acid repeat tracts in the affected proteins, leading to the term, Polyglutamine Diseases, which is applied to this sub-family of diseases. To date, nine distinct genes are known to be linked to polyglutamine diseases, including Hunti

Resumen
The majority of the human genome is comprised of non-coding DNA, which frequently contains redundant microsatellite-like trinucleotide repeats. Many of these trinucleotide repeats are involved in triplet repeat expansion diseases (TREDs) such as fragile X syndrome (FXS). After transcription, the trinucleotide repeats can fold into RNA hairpins and are further processed byDicerendoribonuclases to form microRNA (miRNA)-like molecules that are capable of triggering targeted gene-silencing effects in the TREDs. However, the function of these repeat-associated miRNAs (ramRNAs) is unclear. To solve

Resumen
Abstract Trinucleotide repeats (TNRs) undergo frequent mutations in families affected by TNR diseases and in model organisms. Much of the instability is conferred in cis by the sequence and length of the triplet tract. Trans-acting factors also modulate TNR instability risk, on the basis of such evidence as parent-of-origin effects. To help identify trans-acting modifiers, a screen was performed to find yeast mutants with altered CTG·CAG repeat mutation frequencies. The RTG2 gene was identified as one such modifier. In rtg2 mutants, expansions of CTG·CAG repeats show a modest increase in rate,

TREDs are characterized as neurodegenerative diseases or complex syndromes with significant neurological components.

The human FMR1 (CGG) n array can exhibit genetic instability characterized by progressive expansion over several generations leading to gene silencing and the development of the fragile X syndrome. While expansion is dependent upon the length of uninterrupted (CGG) n , instability occurs in a limited germ line and early developmental window, suggesting that lineage-specific expression of other factors determines the cellular environment permissive for expansion.

Abstract Genetic information can be altered by base substitutions, frameshift mutations, and addition or deletion of nucleotides. Deletions represent an important class of genetic aberration occurring at DNA sequences where it is often possible to predict the existence of intermediates of mutation. Instability within tracts of repetitive sequence have recently been associated with several genetic disorders, including the so-called triplet repeat diseases and certain forms of colorectal cancers. In Escherichia coli, (GpC)n repetitive sequences have been shown to be deletion prone, but the preci

Resumen
Many human hereditary neurological diseases, including fragile X syndrome, myotonic dystrophy, and Friedreich’s ataxia, are associated with expansions of the triplet repeat sequences (TRS) (CGG/CCG, CTG/CAG, and GAA/TTC) within or near specific genes. Mechanisms that mediate mutations of TRS include DNA replication, repair, and gene conversion and (or) recombination. The involvement of the repair systems in TRS instability was investigated in Escherichia coli on plasmid models, and the results showed that the deficiency of some nucleotide excision repair (NER) functions dramatically affects th

Resumen
Length polymorphisms of polyglutamine (polyQs) in triplet-repeat-disease-causing genes have diversified during primate evolution despite them conferring a risk of human-specific diseases. To explain the evolutionary process of this diversification, there is a need to focus on mechanisms by which rapid evolutionary changes can occur, such as alternative splicing. Proteins that can bind polyQs are known to act as splicing factors and may provide clues about the rapid evolutionary process. PolyQs are also characterized by the formation of intrinsically disordered (ID) regions, so I hypothesized t

Цель: описание клинической значимости определения числа CAG-повторов в экзоне 1 гена HTT у пациентов с болезнью Гентингтона в Российской Федерации. Методы. В исследование были включены образцы ДНК 1290 человек, обследованных для уточнения количества CAG-повторов в гене HTT в лаборатории диагностики аутоиммунных заболеваний НМЦ Минздрава России по молекулярной медицине ПСПбГМУ имени акад. И.П. Павлова. От каждого обследованного было получено информированное добровольное согласие. Всем обследованным было проведено исследование количества CAG-повторов в гене HTT методом ПЦР с праймингом тройных п
