  1. Legend for Table 1. In this table we provide the generating frequencies in case and control populations for the thirteen multi-locus genotypes. We number the genotype frequencies 0 – 12. The multi-locus genotype corresponding to each coded genotype (0–12) is given under the heading "Genotype Codings" (see directly below). Note that, at each SNP, we use the code 1, 2, 3 to refer to the less common homozygote, heterozygote, and more common homozygote, respectively. For example, the code "3 : 3 : 3" is the multi-locus genotype consisting of the more common homozygote at each of the three SNP loci. Also note that these generating frequencies suggest a recessive mode of inheritance for AS in our simulations, since greatest risk occurs for individuals who are homozygous for each of the three SNPs (code 3 : 3 : 3).
  2. Genotype Codings:
  3. 0 = 1 : 2 : 2
  4. 1 = 1 : 3 : 3
  5. 2 = 2 : 1 : 1
  6. 3 = 2 : 2 : 2
  7. 4 = 2 : 2 : 3
  8. 5 = 2 : 3 : 2
  9. 6 = 2 : 3 : 3
  10. 7 = 3 : 1 : 1
  11. 8 = 3 : 2 : 1
  12. 9 = 3 : 2 : 2
  13. 10 = 3 : 3 : 1
  14. 11 = 3 : 3 : 2
  15. 12 = 3 : 3 : 3
