Fig. 1: Ancestry contour figure showing cSCC prevalence by genetic ancestry in GERA.

a Hispanic/Latinos (N = 8490 individuals, including 294 cSCC cases); b non-Hispanic whites (N = 78,583 individuals, including 11,028 cSCC cases). cSCC prevalence is indicated on a color scale, with red hues indicating higher prevalence. Axes reflect the first two principal components of ancestry. Nationality subgroup labels were derived from the Human Genome Diversity Project.
