Figure 1From: Genetic determinants of phenotypic diversity in humansClassification of genetic variants by composition. Schematic of sequence and structural variants compared to reference sequence. Sequence variation (indicated by red line) refers to single-nucleotide variants and small (less than 1 kb) indels. Structural variation includes inversions, translocations and copy-number variants, which result in the presence of a segment of DNA in variable numbers compared to the reference sequence, as in duplications, deletions or insertions.
