ATRHunter

ATRHunter identifies approximate tandem repeats (ATRs) in DNA sequences to enable analysis of repeat variation and genomic instability.

Key Features:

• ATR definition: Defines approximate tandem repeats as nucleotide sequences occurring consecutively at least twice with minor variations between repeat units.
• Flexible statistical model: Implements a statistical model that accommodates a broad spectrum of ATR definitions and adjustable search parameters.
• Robust statistical framework: Uses a statistical framework to precisely define ATRs and support accurate detection.
• Efficient algorithm: Employs an algorithm optimized for rapid processing of large genomic datasets.
• Validated accuracy: Demonstrated reliable ATR detection through testing and includes design features to minimize false positives and false negatives.

Scientific Applications:

• Genetic variation analysis: Detection of ATRs to study sequence variation and repeat polymorphisms within genomes.
• Evolutionary studies: Identification of ATRs to investigate repeat evolution and comparative genomics.
• Disease mechanism investigation: Characterization of ATR-associated genomic instability and its potential contributions to disease, including cancer.

Methodology:

Uses a flexible, robust statistical model together with an efficient algorithm developed to define and detect approximate tandem repeats and designed to reduce false positives and false negatives.
