FiLT3r

FiLT3r identifies and quantifies FLT3-internal tandem duplications (FLT3-ITDs) in high-throughput sequencing (HTS) data for acute myeloid leukemia (AML) research.

Key Features:

• Alignment-free k-mer approach: Employs an alignment-free methodology that analyzes k-mers from sequencing reads covering FLT3 exons 14 and 15 to detect ITDs.
• Targeted region analysis: Specifically focuses on reads mapping to FLT3 exons 14 and 15 to capture clinically relevant ITDs.
• Resource efficiency: Minimizes memory usage and processing time for analysis of capture-based HTS datasets.
• High precision: Reported no false positives or false negatives in comparative analyses against state-of-the-art alternatives and the fragment analysis gold standard.
• Validation on diverse datasets: Validated using a cohort of 185 AML patients sequenced with capture-based HTS and on public RNA-Seq data.

Scientific Applications:

• Clinical risk stratification and monitoring: Provides sensitive detection of FLT3-ITDs used for patient risk stratification and clinical follow-up in AML.
• AML research: Enables detection and quantification of FLT3-ITDs in sequencing datasets to support molecular studies of AML cohorts.
• Large-scale genomic studies: Supports scalable analysis of capture-based HTS and RNA-Seq datasets for cohort-level identification of FLT3-ITDs.

Methodology:

Alignment-free analysis using k-mer extraction and analysis from sequencing reads covering FLT3 exons 14 and 15.
