Tandem repeat disorders

Tandem Repeat History Re

Expandable DNA Repeat and Human Hereditary Disorders

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. One the most frequently occurring types of mutation is trinucleotide repeat expansion. The present study was conducted with the aim of investigating the cause...

TROLL-Tandem Repeat Occurrence Locator

SUMMARY Tandem Repeat Occurrence Locator (TROLL), is a light-weight Simple Sequence Repeat (SSR) finder based on a slight modification of the Aho-Corasick algorithm. It is fast and only requires a standard Personal Computer (PC) to operate. We report running times of 127 s to find all SSRs of length 20 bp or more on the complete Arabdopsis genome--approx. 130 Mbases divided in five chromosomes-...

Sequence analysis TRAL: tandem repeat annotation library

Motivation: Currently, more than 40 sequence tandem repeat detectors are published, providing heterogeneous, partly complementary, partly conflicting results. Results: We present TRAL, a tandem repeat annotation library that allows running and parsing of various detection outputs, clustering of redundant or overlapping annotations, several statistical frameworks for filtering false positive ann...

A tandem repeat gene in a picornavirus.

Three closely related genes for the small genome-linked protein (VPg) of picornaviruses have been identified by sequence analysis as a tandem repeat in the genome of Foot and Mouth Disease Virus (FMDV), strain O1K. This unusual structure was also found in the genome of strain C1O, belonging to a different FMDV serotype. Predicted biochemical properties of the three VPg gene products are in exce...
