Table 4 Structural variants in the FVB/NJ genome

	Deletion	Duplication	Inversion	Insertion	Deletion in gain	Deletion + insertion	Inversion + deletion or insertion
Total	15,358	137	67	14,246	58	111	71
Genes	280	109	1	20	2	0	4

Listed are the number of SVs by type, and the number of genes with at least one protein-coding exon overlapping a SV. The following SV types involve more than one SV and have been described by Yalcin et al. [15, 28]: a 'deletion in gain' is a deletion that is found within a duplicated region; a 'deletion plus insertion' is a deletion that co-occurs with an insertion; and an 'inversion plus a deletion or insertion' is an inversion flanked by one or more deletions or insertions.
