2. Figure 1
Next-generation sequencing (NGS) bioinformatics pipeline. The figure illustrates a bioinformatics pipeline and its components that are typically used for processing NGS data. The illustration may not represent nuances or additional algorithms that are specific to sequencing platforms. The components of the pipeline that overlap with the gray shaded region are out of scope of this guideline. BAM, binary alignment map; HGVS, Human Genome Variation Society; indel, insertion/deletion; QC, quality control; SNV, single-nucleotide variant; VCF, variant call format.

3. Figure 2
Systematic literature review. The figure summarizes the strategy that was used to search the PubMed database for identifying articles for systematic literature review. The asterisk indicates a wildcard character meaning that the characters starting at the asterisk can be anything. [All Fields], all PubMed fields were searched for the term indicated; NGS, next-generation sequencing.

4. Figure 3
Example of a horizontally complex variant. An example of a horizontally complex variant in exon 19 of the EGFR gene ( accession number NM_ : c.2236_2253delinsTTG: p.E746_T751delinsL). One deleted sequence is flanked by a deleted sequence on the left and a single-nucleotide change on the right. These individual variants (two deletions and one single-nucleotide substitution) represent a single haplotype, which is a well-characterized activating EGFR variant with therapeutic significance.

5. Figure 4
Example of a vertically complex variant. An example of a vertically complex variant in exon 2 of the KRAS gene ( accession numberNM_ : c.35G>A:p.G12D; NM_ : c.35G>T:p.G12V). The representative image of the sequence pileup demonstrates three alleles (one reference and two alternative alleles) at the same genomic position.
