CNV proportions across genomic regions and homozygous deletions.

<p>(<b>A</b>) Proportion of deletions (white) and duplications (black) overlapping four mutually exclusive genomic categories; entirely within intergenic regions, entirely within intronic regions, partially overlapping a gene including an exonic region, or completely overlapping at least one gene. (<b>B</b>) Read depth coverage (grey histograms) along a gene (blocks are exons) for one representative individual from each population, showing CNV deletions. Examples include an intronic loss from a small G protein signaling modulator 3 gene (<i>SGSM3</i>) in Atlantic individuals, an exonic partial gene loss of a carbonic anhydrase gene (<i>CA4</i>) in Norwegian individuals, and the complete gene loss of a pogo transposable element with <i>KRAB</i> domain gene (<i>POGK</i>) in Atlantic individuals.
