variant calling
Definition
The computational process of identifying genetic variants (SNPs, indels, structural variants) by comparing aligned sequencing reads to a reference genome. Variant callers use statistical models to distinguish true biological variants from sequencing errors and artifacts. Common tools include GATK, DeepVariant, and FreeBayes, with outputs in VCF format.
In Practice
variant calling is widely used in genetics & genomics and related fields. Key applications include:
- Research and experimental design in molecular biology laboratories
- Clinical diagnostics and therapeutic development pipelines
- Automated validation within VigyanLLM's 24-step primer design and analysis framework
