Designated for rs1042602*C/A = 1/2 - rs1126809*G/A = 1/2
Protein phases designated at S192Y-R402Q as 192S = 1, 192Y = 2; 402R = 1, 402Q = 2
Based on a four point scale S-R = 3, Y-R =2, S-Q =1, Y-Q = 0
Sample set of 5,394 for skin colour,
Sample set of 5,393 for hair colour,
Sample set of 4,942 for eye colour, in BTNS and/or melanoma cases in which haplotype phase was predicted from the MENDEL program
