SNV calling from NGS data involves identifying single nucleotide variants from raw sequencing data, and there are a variety of synonyms and terms used to describe this process. Some experts refer to this as SNP or variation calling, while others use phrases such as genomic variant detection or genetic variant discovery. Additionally, there are also more specialized terms such as somatic mutation detection or germline variant analysis, which are used to describe specific applications of SNV calling. Ultimately, regardless of the specific word choice, the goal of SNV calling is to accurately identify and characterize genetic variation, providing insight into the underlying biology of the genome being studied.
