FastQValidator

FastQValidator validates FastQ files for format compliance and sequencing-quality metrics to support reliable downstream analyses such as exome sequencing and variant detection.

Key Features:

• Standard Compliance: Checks FastQ files against predefined format and content standards to ensure they meet criteria for subsequent bioinformatics processing.
• Quality Metrics Assessment: Evaluates sequencing quality metrics within FastQ files to identify potential issues that could affect variant calling and analysis.
• Depth-of-Coverage Analysis: Examines depth of coverage metrics to detect variability across targeted regions.
• Identification of Annotation-affecting Issues: Detects site-specific coverage variability and other data quality problems that can complicate variant annotation.

Scientific Applications:

• Exome sequencing quality control: Validates input data for exome studies including those using the Agilent SureSelect Human All Exon 50 Mb kit and Illumina HiSeq 2000 platform (2×100 bp).
• Molecular diagnosis and variant prioritization: Supports reliable variant detection and annotation in genetic research and molecular diagnosis of disorders such as limb-girdle muscular dystrophy, including interpretation of variants like desmin IVS3+3A>G and filamin C p.W2710X.

Methodology:

Examines sequencing data quality metrics and depth of coverage to identify variability at specific sites that may affect variant annotation.
