Distribution of genotypes of the tSNPs with significant difference in cases and controls. Codominant 1, homozygous including risk allele versus homozygous including non-risk-allele; Codominant 2, heterozygous versus homozygous including risk allele. Sum of the genotype frequencies may not be 100% due to the rounding at one decimal positions. a: The value was not showed due to the rounding at one decimal positions
