Penetrance matrix of MC1R coding variants. Combinations of all coding variants plus the non-coding variant rs3212379, located close to the 5′ end of MC1R. Depth of shading in green indicates the % of the genotype with red hair, also indicated by the rounded numbers. Cells filled in black have no data. Full data are in Supplementary Table 2
