Evolutionary conservation of HERC2/OCA2 genomic region. ATP10A, GABRB3, GABRA5, GABRG3, OCA2, and HERC2 genes are indicated in the human genomic segment of the chromosome 15. In the other species, the same colors identify the orthologous genes. The chromosome of each species containing the indicated region is indicated on the left side. Scale bars (Mb: Mega base pairs) indicate the position along the chromosome, as obtained by the UCSC genome browser (https://genome.ucsc.edu, accessed on 15 February 2024). Human, Homo sapiens; chimp, Pan troglodytes; mouse, Mus musculus; shrew, Sorex araneus; chicken, Gallus gallus; lizard, Anolis carolinensis; xenopus, Xenopus tropicalis; zebrafish, Danio rerio. Data from each genomic region are presented in Supplementary Tables S1 and S2.
