^*Number of deduced ancestral gene arrays (prior to the SV formation) with a given total OPN1LW and OPN1MW copy number among BCM-linked SVs.

^†Number of subjects with experimentally determined total OPN1LW and OPN1MW copy number in healthy controls. Shadings distinguish groups of subjects with three or fewer and more than three OPN1LW/MW gene copies, respectively.
