NGS Variant Calling Using GATK Pipeline in Human Genomics

The NGS variant calling workflow relies on a standardized computational pipeline to transform raw nucleotide read data from Next-Generation Sequencing (NGS) into structurally annotated genomic variants. This theoretical framework defines the conversion of massive FastQ files, representing unprocessed sequence reads, into Variant Call Format (VCF) files containing specific component fields that denote genetic alterations. The process operates within human genomics and molecular biology domains to decode biological information while establishing boundary conditions where microbial data requires distinct analytical paradigms not covered by this universal mammalian pipeline.
