Tools for the identification of variable and potentially variable tandem repeats

Area of Science:

• Bioinformatics
• Genomics
• Molecular Biology

Background:

• Tandem repeat arrays exhibit variations across populations, strains, and species, potentially influencing biological functions.
• The proliferation of genomic data necessitates tools for characterizing variability in these repeat sequences.

Purpose of the Study:

• To develop and present computational tools for identifying and predicting variable tandem repeats.
• To aid researchers in analyzing sequence length variation within tandem repeat arrays.

Main Methods:

• Development of a software suite including VNTRfinder (Variable Number of Tandem Repeats finder).
• VNTRfinder detects sequence length variations in inter-specific and intra-specific tandem repeats.
• Predictive capabilities are offered for identifying potentially polymorphic tandem repeats in the absence of comparative sequences.

Main Results:

• Successful identification of programs for detecting tandem repeat variation across multiple sequences.
• VNTRfinder enables precise measurement of sequence length variation in tandem repeat arrays.
• Predictions are generated to guide experimental focus on highly variable tandem repeats.

Conclusions:

• The developed tools serve as a valuable resource for studying tandem repeats with clinical and evolutionary significance.
• The tools are accessible online and available as downloadable versions for various operating systems.
• These resources facilitate deeper investigation into the functional roles of tandem repeat variability.
