Table II. Enrichment of CNV within subclasses of genes

For all eligible NB-encoding and RLP-encoding genes, significant differences between the number of genes for a given gene category located in CNV regions in comparison with non-CNV regions were determined by Fisher’s exact test (*P < 0.05, **P < 0.001). na, Not applicable.

  • a %CNV is calculated as the number of CNV in a particular category divided by the total number of genes in that category.

  • b Fold change is relative to the genome-wide %CNV: the %CNV for a particular category divided by genome-wide %CNV (1.5%).
